User questions & answers

Question:	Does it detect ceiling joist
Answer:	Hello Donna. Yes, the A100 will locate ceiling joist. Thank you.
Question:	What is the difference between e50 and A100? And which is better? Thanks
Answer:	All i know is that e50 did not work for me. I tired both settings and gave me fake results. Directions are simple. Did not work. I drilled into space.
Question:	Would this work on bathroom/shower tiles? Trying to install grab bars in the shower area
Answer:	Hello Ashley. No, while the A100 can scan through tile sometimes the layers behind the tile, the hardi-backer board and glue, can be problematic. We recommend using the A200 on bathroom tiles. The A200 has an additional metal scan feature on it, if you are not able to get a consistent reading using the Studscan or Deepscan mode you can use the metal scan feature on this tool to find the nails holding the wall boards in the studs. Thank you.
Question:	will this signal if there is a stash in the wall also, just like studs
Answer:	haven't come across one in my walls yet.

Zircon StudSensor A100

The SS A100 is a handheld tool dedicated to quickly and efficiently find the edges of studs and alert you of live AC wiring. The A100 comes equipped with 2 scanning modes: StudScan and DeepScan.

Locate Studs and Scan for Live AC Wiring Safely and Efficiently

The Zircon StudSensor A100 makes scanning easy with its newly designed ergonomic grip. The tool's StudScan finds shallower wood or metal studs up to 0.75 in. (19 mm) deep. Slide the Mode Selector Switch to DeepScan Mode. This doubles the scanning depth to 1.5 in. (38 mm) deep and allows for increased accuracy on deeper targets.

The A100 also includes WireWarning Detection that automatically operates in StudScan and DeepScan Modes. This safety feature alerts you to the presence of live, unshielded electrical AC wires while scanning for studs.

Before use, always be sure to install a brand new 9V alkaline battery. Zircon stud finders, particularly those with screens, require and consume a great deal of current from batteries. For optimal performance, brand-new, recently purchased alkaline batteries with an extended expiration date, are strongly recommended for use in these tools.

Edge Finding

Before scanning, hold the A100 flat against wall and press the Power Button to calibrate. Be sure not to move the scanner while calibrating. After a short beep sounds, confirming calibration is complete, continue pressing the Power Button and slide the scanner slowly against the surface.

Be sure not to drill at the edge of the stud. Continue to scan the surface until the stud's center is detected.

The easy-to-read screen will alert you as the stud detector approaches the edge of the stud in both scanning modes. Once the edge is detected, the patented arrow-shaped SpotLite Pointer will shine, the translucent base will illuminate, and an audio tone will sound. DO NOT DRILL HERE! Instead, mark the spot in the “V’ marker groove at the head of the tool and continue past the stud. Repeat the process in the opposite direction and mark the opposite edge of the stud. The center of the stud is midway between the two marks.

The center of the stud center is the stud's most secure location. It is critical to drill in the center when mounting heavy objects.

StudScan and DeepScan Modes

Use StudScan Mode to find the edges of wood or metal studs up to 0.75 in. (19 mm) deep.

For best results, always start in StudScan Mode when looking for studs.

If StudScan Mode provides irregular readings the studs might be behind deeper than 0.75 in. (19 mm). Slide the Mode Selector Switch to DeepScan Mode. This doubles the scanning depth to 1.5 in. (38 mm) deep and allows for increased accuracy on deeper targets.

Note: WireWarning Detection works in both StudScan and DeepScan Modes. The WireWarning Detection Icon will flash when live, unshielded wires are detected.

WireWarning Detection

Safely Scan in both Modes

WireWarning Detection is a feature that is always on while scanning in StudScan and DeepScan Modes.

It alerts you to the presence of live, unshielded, electrical AC wires up to 2 inches (50 cm) deep.

As you approach an area with live AC voltage, a lightning bolt icon will display on the screen. This the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, the WireWarning Detection Icon will flash.

Note: Please turn off the electricity and use extreme caution in areas where live AC voltage is detected before nailing or drilling.

Frequently Asked Questions

Question: Does the StudSensor A100 include a battery?

Answer: No. Zircon stud finders and detectors, particularly those with screens, require and consume a great deal of current from batteries. For optimal performance, a brand-new, recently purchased 9V alkaline battery with an extended expiration date, is not included but is required to properly power the A100.

Question: I inserted a 9V battery, but the tool doesn't turn on or is giving me strange readings. Is my tool broken?

Answer: Please be sure to use a fresh, brand new 9V alkaline battery with an extended expiration date. Batteries that may work in a smoke detector or remote control may not have adequate voltage to power the sensing technology in StudSensors.

Question: Does this tool need to be calibrated?

Answer: Yes, as with all Zircon tools, the StudSensor A100 needs to calibrate to the surface before scanning. Calibrating the tool on an empty wall gives the device a chance to measure the wall thickness and material density, as well as register factors like humidity, temperature, and even the minor electric readings from your hand, which all have an impact on the readings from the wall. Calibrating is easy and just takes a second. To calibrate, simply place the unit flat against the surface to be scanned and press the Power Button. When powering the A100 on, all the icons on the screen and the SpotLite Pointing System will briefly flash and the tool will beep. After this occurs, the screen will then clear and, depending on the selected mode, the words "StudScan" or "DeepScan" will remain, indicating that calibration has occurred and the tool is ready to begin scanning. It is important not to move the tool or begin scanning until the calibration process has taken place for the most accurate results.

Question: What is DeepScan Mode?

Answer: Unlike StudScan Mode, which scans through one layer of drywall up to 0.75 in. thick (19 mm), DeepScan Mode scans through 2 layers of drywall up to 1.5 in. (38 mm) deep. DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling. Extra layers in a wall can make it difficult to find studs in regular StudScan Mode. To minimize false positives and/or finding other objects further behind the wall that may not be a stud, always start your scan in StudScan Mode first.

Question: How can I be certain the objects found behind my wall are studs in DeepScan Mode?

Answer: DeepScan Mode has increased sensitivity so you may have located something other than a stud. Studs are equally spaced to either side (12, 16, or 24 in. apart) and typically run from floor to ceiling. To better confirm that what you found is a stud, check for other studs equally spaced to either side and for the same stud at several heights directly above and below the first stud indication. A stud reading would also measure approximately 1.5 in. (38 mm) apart from each edge. Anything larger or smaller may not be a stud if not near a door or window.

Question: Will this StudSensor A100 locate metal studs?

Answer: Yes, the A100 will locate metal studs in StudScan, DeepScan, and Metal Scan Modes. Since stud finders are looking for a change in density behind drywall, not a particular material, in StudScan and DeepScan Modes the detector will react to metal studs the same as it would for wooden studs. The A100 will locate wood and metal studs up to 0.75 in. (19 mm) deep while DeepScan Mode locates targets up to 1.5 in. (38 mm) deep.

Question: Why does the tool beep and the lights flash when scanning for a stud?

Answer: The tool could've been calibrated over a stud, calibrated on a dense part of the wall, or the back of the unit may have slightly lifted or tilted during the scan. Move the StudSensor A100 over a couple of inches to the left or right, re-calibrate, and start your scan again.

Question: What is WireWarning Detection?

Answer: WireWarning Detection is a feature that is always on while you are scanning in StudScan and DeepScan Modes to alert you to the presence of live, unshielded electrical AC wires up to 2 in. (50 mm) deep. As you approach an area with live AC voltage, a lightning bolt icon will display on the screen. This is the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, this icon will flash. PLEASE TURN OFF THE ELECTRICITY AND USE EXTREME CAUTION IN AREAS WHERE LIVE AC VOLTAGE IS DETECTED BEFORE NAILING OR DRILLING.

Question: Why does the area of voltage appear much larger than an actual wire?

Answer: Static charge may develop on drywall, spreading voltage detection as much as 12 in. (30 cm) laterally from each side of an actual wire. To narrow detection, turn the tool off and on again at the edge of where the wire was first detected and repeat the scan.

Question: I suspect electrical wires in a certain area when I scan, but why am I not detecting any?

Answer: Wires may be shielded in metal conduit or behind a metallic wall covering. It could also be that the wire is deeper than 2 in. (50 mm) or that the wire may not be live (hot). Always exercise extreme caution when working near electricity.

Question: Does the A100 work on wood paneling and other wood surfaces?

Answer: The A100 is optimized to scan through standard interior sheetrock / drywall (gypsum) construction. This tool will work on wood, plywood, wood paneling and particle board up to 1.5 in. (38 mm) thick when in DeepScan Mode.

Question: Will the A100 work on textured wall surfaces, acoustic ceilings, or wall paper?

Answer: Yes, the A100 will work on textured surfaces and dried wall paper as long as it does not contain any metallic foil or fibers. For highly textured walls or acoustic ceilings, place or tape a thin piece of cardboard onto the surface to be scanned. Recalibrate and scan over the cardboard in DeepScan Mode.

Question: Can I use this tool to find studs behind carpet?

Answer: No. Zircon tools are designed for hollow interior walls. They will generally work well to find studs or joists through a plywood subfloor, after the carpeting/flooring has been removed.

Question: Will the A100 work on ceramic tile?

Answer: While the StudSensor A100 may be able to scan through ceramic tile in DeepScan mode to locate studs, the many variable layers behind tiled surfaces make it one of the more difficult scanning environments.

Question: Does this StudSensor work on lath and plaster?

Answer: No. Due to irregularities in plaster thickness, this tool is not recommended for use on lath and plaster.

Question: Can I use this tool to scan the outside wall of my house?

Answer: No. Zircon StudSensors are designed and recommended for interior use only.

Question: I'm planning to mount my new flat screen TV to the wall. Will this tool help me?

Answer: Yes. The A100 is ideal for basic home or office projects. The center-finding technology allows you to easily find and mark the center of the stud for secure mounting of TV's and AV equipment, closet or garage shelving, heavy mirrors, light fixtures, coat racks and more.

Question: Is the tool waterproof?

Answer: No. The StudSensor A100 is splash and water resistant, but not waterproof.

Question: What is the difference between magnetic and electronic stud finders?

Answer: Magnetic stud finders are simply magnets that look for anything magnetic behind a wall. Typically, they are advertised to find screws or nails that hold the wall surface to the studs. However, nails often times are not placed in the center of studs, making it difficult to determine where the stud's center is or how wide the stud is.

Electronic stud finders, such as the A100, on the other hand, operate by detecting density changes behind a surface (like a wall) and will clearly and precisely indicate the edges and center of a stud. The center of a stud is the most secure location when mounting anything heavy. For applications like mapping out floor joists, electronic stud finders have an advantage over magnets because they are not attracted to nails holding floor boards to a subfloor, as well as nails in joists.

Question: Does the StudSensor A100 come with a warranty?

Answer: The StudSensor A100 includes limited one year warranty when fulfilled by and shipped from Amazon.

Question: Where can I get help using my StudSensor A100?

The SS A150 is a handheld tool dedicated to quickly and efficiently find studs and alert you of live AC wiring. The A150 comes equipped with 2 scanning modes: StudScan and DeepScan.

Locate Studs and Scan for Live AC Wiring Safely and Efficiently

The Zircon StudSensor A150 makes scanning easy with its newly designed ergonomic grip. The tool's StudScan finds shallower wood or metal studs up to 0.75 in. (19 mm) deep. Simply press the Power Button twice to double the scanning depth to 1.5 in. (38 mm) in DeepScan Mode.

The A150 also includes WireWarning Detection that automatically operates in StudScan and DeepScan Modes. This safety feature alerts you to the presence of live, unshielded electrical AC wires while scanning for studs.

Before use, always be sure to install a brand new 9V alkaline battery. Zircon stud finders, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, brand-new, recently purchased alkaline batteries with an extended expiration date, are strongly recommended for use in these tools.

StudScan and DeepScan

Use StudScan Mode to find the center, edges, and direction of wood or metal studs up to 0.75 in. (19 mm) deep.

For best results, always start in StudScan Mode when looking for studs.

If StudScan Mode provides irregular readings, or the Signal Strength Indicator is weak, the studs might be behind deeper than 0.75 in. (19 mm). Quickly press the Power Button twice and hold it down after the second press to switch to DeepScan Mode. This doubles the scanning depth to 1.5 in. (38 mm) deep and allows for increased accuracy on deeper targets.

Before scanning, hold the A150 flat against wall and press the Power Button to calibrate. Be sure not to move the tool while calibrating. After a short beep sounds confirming calibration is complete, continue pressing the Power Button and slide the tool slowly against the surface.

When the A150 finds the edges and center of a stud, 'Edge' and 'Center' displays respectively, indicating you have found your target. When the stud's center is located, the SpotLite Pointer also illuminates and a short beep sounds.

The center of the stud is the stud's most secure location. It is critical to drill in the center of a stud when mounting heavy objects.

Note: WireWarning Detection works in both StudScan and DeepScan Modes. The WireWarning Detection Icon will flash when live, unshielded wires are detected.

WireWarning Detection

Be Alerted of Electrical Wires in Both Modes.

WireWarning Detection is a feature that is always on while scanning in StudScan and DeepScan Scan Modes.

It alerts you to the presence of live, unshielded, electrical AC wires up to 2 inches (50 cm) deep.

As you approach an area with live AC voltage, a lightning bolt icon will display on the LCD screen. This the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, the WireWarning Detection Icon will flash.

Note: Please turn off the electricity and use extreme caution in areas where live AC voltage is detected before nailing or drilling.

Auto Correcting Technology (ACT)

Automatically Have Common Errors Corrected.

This feature enables the tool to automatically adjust for common calibration errors. It checks calibration 10 times per second and automatically recalibrates when/if needed. If scanning begins directly over a stud, the tool will transparently recalibrate, so you don't have to, and will find that stud when you scan back over it.

This recalibration is usually transparent and no indication is made. If an arrow icon illuminates, the tool was calibrated near or over a stud and then moved away. The arrow indicates the direction of the missed stud.

Frequently Asked Questions

Question: Does the StudSensor A150 include a battery?

Answer: No. Zircon stud finders and detectors, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, a brand-new, recently purchased 9V alkaline battery with an extended expiration date, is not included but is required to properly power the A150.

It is important not to move the tool or begin scanning until the calibration process has taken place for the most accurate results.

Question: What does 'Center Finding' mean?

Answer: Center Finding stud finders locate both the edges AND the center of wood and metal studs and joists in one step. 'Edge Finding' stud finders, on the other hand, only find the edges of studs, so you must determine the center. Finding the center of the stud to mount heavy objects is critical as the stud's center is the most secure location of the stud.

Question: What is DeepScan Mode?

Answer: Unlike StudScan Mode, which scans through one layer of drywall up to 0.75 in. thick (19 mm), DeepScan Mode scans through 2 layers of drywall up to 1.5 in. (38 mm) deep. DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling.

Question: Does this StudSensor work on lath and plaster?

Answer: No. Due to irregularities in plaster thickness, this tool is not recommended for use on lath and plaster.

Question: What does the Signal Strength Indicator do?

Answer: To help you filter out the target from potential decoys that would give the A150 a false reading, the Signal Strength Indicator gives a reading of the strength, or the certainty, of the returning signal from the wall. Three bars (the highest level) indicates an obvious result behind a normal wall, while two bars (or below) indicates that while the device has found something, it may either be a smaller object than your target, or the target is behind an extra thick wall. Since every wall is built differently, and since any wall can have pipes, wires, or other objects behind it that can return a result, you can use the Signal Strength Indicator to 'map out' your wall to determine the target from the other objects.

Question: Can I use this tool to scan the outside wall of my house?

Answer: No. Zircon StudSensors are designed and recommended for interior use only.

Question: I'm planning to mount my new flat screen TV to the wall. Will this tool help me?

Answer: Yes. The A150 is ideal for basic home or office projects. The center-finding technology allows you to easily find and mark the center of the stud for secure mounting of TV's and AV equipment, closet or garage shelving, heavy mirrors, light fixtures, coat racks and more.

The Key to Success is in the Battery

A new, fully charged 9V battery is required to steadily power the integrated LCD screen in Zircon tools. Please note that, like a cell phone or any personal electronic device, the 9V batteries needed to power Zircon tools can lose power even when sitting idle. The installation of a fresh battery, with an extended expiration date, typically resolves 99% of problems seen by Zircon Customer Support.

Find the Edges and the Center of Studs

1. StudScan Mode:

Use this mode to find the center, edges, and direction of wood or metal studs up to 3/4 inches (19 millimeters) deep. For best results, always start in this mode when looking for studs.

Note: WireWarning detection works in all modes. The indicator flashes on the screen when detecting a live, unshielded wire.

2. DeepScan:

If Stud Scan mode provides irregular readings, or the Signal Strength Indicator is weak, the studs might be behind more than ¾ inches (19 millimeters) of drywall Quickly push the handle of the device downward twice to switch into DeepScan mode. This doubles the scanning depth to 1½ inches (38 millimeters) deep and allows for increased accuracy on deeper targets.

Note: WireWarning detection works in all modes. The indicator flashes on the screen when detecting a live, unshielded wire.

Metal Scan Mode Detects Both Ferrous and Non-Ferrous Metal

3. Metal Scan Mode:

Use this mode to locate and avoid hazards such as pipes behind walls. Metal Scan mode detects non-ferrous metal such as copper pipe up to 1½ inches deep, and ferrous metal such as rebar, up to 3 inches deep.

Use Metal Scan mode to differentiate between metal and wood studs. First, find the stud in StudScan mode. Then, switch to Metal Scan mode and run the MS 740 up and down the stud. The tool alerts in a pattern as it detects the drywall screws in the wood for wooden studs. The unit alerts along the length of the studs with metal studs

Note: WireWarning detection works in all modes. The indicator flashes on the screen when detecting a live, unshielded wire.

AC Scan Mode Helps Find and Trace Live, Unshielded Wires

4. AC Scan Mode:

In this mode, the LCD screen finds live, unshielded, electrical wires up to 2 inches (51 millimeters) deep. Move the MS 740 slowly across the surface and the signal indicates the proximity of the source. Mark where the strongest signal appears. Continue this process to track the wires through the walls.

Integrated Marking Tool for Easy One-Handed Operation

The MS 740’s integrated erasable marker allows easy, one-handed operation. When the target is found, simply push down on the 'mark' button. The pencil marks the surface without interrupting the scan. The MS 740 comes with a pencil pre-installed, and refills in the box.

Frequently Asked Questions:

Question: What is the scanning depth for the MultiScanner 740?

Answer: The MS 740 scans up to the following depths:

- Stud Scan: ¾ in (19mm) deep.

- DeepScan: 1½ in (38mm).

- Metal Scan: 3 in (76mm).

- AC Scan: 2 in (51 mm).

Question: How can I tell if I’m in DeepScan mode?

Answer: When the MultiScanner 740 is in DeepScan mode, the STUDSCAN indication on the LCD flashes continuously.

Question: How can I be certain the object found behind my wall is a stud when in DeepScan mode?

Answer: The increased sensitivity in DeepScan mode may have located something other than a stud. Studs are equally spaced to either side (12, 16, or 24 in. apart) and typically run from floor to ceiling. To better confirm that what you found is a stud, check for other studs equally spaced to either side 12, 16, or 24 in. apart or for the same stud at several heights directly above and below the first stud indication. A stud reading also measures approximately 1 ½ in. (38 mm) apart from each edge.

Question: The stud finder seems to be detecting more targets than there should be. What am I doing wrong?

Answer: There may be electrical wiring and/or metal or plastic pipes near or touching the back surface of the wall. Switch to Metal Scan mode where, combined with WireWarning detection, pipes and electrical wiring should be detected adequately. You can also check for studs equally spaced to either side (12, 16, or 24 in. apart).

Question: Can I find studs behind lath and plaster construction?

Answer: Yes. Using Metal Scan mode, you can identify a stud behind the lath and plaster wall by locating the pattern of nail or screw heads attaching the wood lath to the studs. The nails or screws should be found in a column when scanning for metal. However, if the plaster has metal mesh reinforcement, MultiScanner 740 may be unable to detect studs through that material.

Question: Can I use this scanner on the exterior of my home?

Answer: No. Zircon StudSensors are designed and recommended for interior use only.

Question: I am having difficulty detecting metal, what can I do to remedy this?

Answer: Recalibrate the tool in another location. The tool could’ve been calibrated over, or close to, a metal object, reducing sensitivity. The metal target could also be too deep; if this is the case scan in both horizontal and vertical directions. Metal sensitivity is increased when metal object is parallel to the sensor, located at the front end of the scanner beneath the cross hairs.

Question: I suspect electrical wires in a certain area when I scan, but why am I not detecting any?

Answer: Wires may be shielded in metal conduit or behind a metallic wall covering. It could also be that the wire is deeper than 2 in. or that the wire may not be live (hot). Try the Metal Scan mode to see if you can find metal, wire, or metal conduit. Always exercise extreme caution when working near electricity.

Question: Is the tool waterproof?

Answer: No. The MultiScanner 740 is splash and water resistant, but not waterproof.

Question: What is the difference between AC Scan and WireWarning detection?

Answer: Most Zircon StudSensors have WireWarning detection that indicates when the tool is in the vicinity of live AC voltage. Tools with the WireWarning detection feature continuously detect hot electrical wires (unshielded) up to 2 inches deep while you are scanning for studs or metal. The WireWarning detection is always on, in all modes, to alert you to the presence of hot, unshielded AC wires behind the wall. Depending on the model, either an LED light or an icon on the screen will appear when live AC voltage is being indicated.

In addition to WireWarning detection, some tools also have a dedicated AC Scan Mode. The difference between WireWarning detection and AC Scan Mode is the user interface. WireWarning detection is indicated by a light or icon that is either on or off. In AC Scan mode the bars on the LCD screen indicate when the tool is moving towards the source of the voltage or away from the source of the voltage. Both WireWarning detection and AC Scan Mode may indicate over a smaller or larger zone around the wire depending on conditions. Both features allow the user to interactively calibrate the sensitivity to AC voltage. If the unit indicates over a large area the user can re-calibrate the unit closer to the source of AC in order to reduce sensitivity so the unit will indicate AC over a smaller zone around the wire.

Question: What can this product do in terms of wire tracing?

Answer: Zircon tools with AC Scan Mode are not full featured wire tracers, however when users are mapping a section of a wall AC Scan Mode can assist them in locating the route a wire takes through that section of the wall.

Question: Where can I get help using my MultiScanner?

Answer: Technical Support is available Toll Free on our Customer Support Number 8:00am – 5:00pm Mon – Fri PST or on the Zircon Website.

User questions & answers

Question:	Will it work with brick walls
Answer:	Hi. If your drywall is attached to a layer of plywood that is attached to the stud(s), then, yes, it can work. Keep in mind, the "stud scan" mode is designed (optimized) for a single layer of 1/2" drywall. Any surface thicker than that, you would need to use the "deepscan" mode. The deepscan mode scans down approx. 1&1/2". Please feel free to contact us. Technical and product support services are available free of charge during normal business hours Mon. thru Fri. 8:00am to 5:00pm PST. Please visit the Zircon website for contact info. Thank you.
Question:	Question before i send this a250 back. the scanner was inside an unsealed bubble-wrap bag inside shipping box. no packaging. is this normal
Answer:	Hi. Zircon does not manufacture a case for this scanner, however there are third party offerings you will find on Amazon. Just search : "zircon stud finder" in tools and home improvement. There are a few offerings available. I hope this information is helpful. Thanks.
Question:	Can this find studs behind composite/concrete siding
Answer:	Hello Pablo. No it is not able to find PVC water pipes. Thank you.
Question:	Does it come with a case
Answer:	If your house was constructed using metal studs then - perhaps. I had a hard time getting mine to pick up a stud. I was installing a shelf at my sister-in-law's Condo and could not get it looking ok where the studs were "detected" so, I went with the screw in wall board type. 1st one was destroyed because there was a stud there so, draw your own conclusions.

Product features

Zircon MultiScanner A250

The MS A250 is a handheld tool dedicated to quickly and efficiently find studs, detect metal and scan for live AC wiring. The A250 comes equipped with 4 scanning modes: StudScan, DeepScan, Metal Scan and AC Scan.

4 Mode Multifunctional Wall Scanner with Backlit Display

The Zircon MultiScanner A250 makes scanning easy with its newly designed ergonomic grip. The scanner's StudScan and DeepScan Modes locate the edges and center of wood and metal studs and joists behind walls, floors and ceilings. StudScan finds shallower wood or metal studs up to 0.75 in. (19 mm) deep while DeepScan doubles the scanning depth to 1.5 in. (38 mm).

Metal Scan locates both non-ferrous (non-magnetic) metal, such as copper pipe, and ferrous (magnetic) metal, such as rebar. The A250 is able to detect non-ferrous metal up to 1 in. (25 mm) deep, and ferrous metal up to 3 in. (75 mm) deep.

AC Scan Mode allows you to narrow the location of live AC wiring up to 2 in. (50 mm) deep. With AC Scan, the MS A250's display changes to indicate when the tool is moving towards or away from live electricity. This enables you to adjust the tool's sensitivity to the live AC. This procedure can be repeated multiple times, as needed.

The A250 WireWarning Detection feature automatically operates in StudScan, DeepScan and Metal Scan Modes. This safety feature alerts you to the presence of live, unshielded electrical AC wires while scanning for studs and metal.

Before use, always be sure to install a brand new 9V alkaline battery. Zircon scanners, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, brand-new, recently purchased alkaline batteries with an extended expiration date, are strongly recommended for use in these tools.

AC Scan

Scan Live (Hot) Unshielded Wires.

AC Scan Mode finds live, unshielded electrical wires up to 2 in. (50 mm) deep.

Before scanning, hold the A250 flat against wall and press the Power Button to calibrate. Be sure not to move the scanner while calibrating. After a short beep sounds confirming calibration is complete, continue pressing the Power Button and slide the scanner slowly against the surface.

Mark the spot where the most middle bars display. Continue in same direction until bars reduce, then reverse direction. Mark the spot where the display bars peak.

The midpoint between the two marks is the location of the live AC wiring.

Continue this process to track the wires through the walls.

Always turn off power when working near electrical wires (except when scanning)

Metal Scan

Detect Both Ferrous and Non-Ferrous Metal

Use Metal Scan Mode to locate and avoid hazards, such as pipes, behind walls and determine if a stud is wood or metal.

Metal Scan Mode detects non-ferrous metal, such as copper pipe, up to 1.5 in. (38 mm) deep, and ferrous metal, such as rebar, up to 3 in. (75 mm) deep.

To use, be sure to first calibrate the A250. For maximum sensitivity, press and hold the Power Button while holding the scanner away from the surface. Once a short beep sounds confirming calibration is complete, place against the surface to be scanned. Be sure to continue to hold the Power Button.

Just like in AC Scan Mode, slowly slide the scanner across the surface and mark the spot where the most display bars peak. Continue scanning until the bars reduce and reverse the direction.

The midpoint between the two marks is the location of the metal target.

Note: WireWarning Detection works in Metal Scan Mode. The Live AC Icon will appear when live, unshielded wires are detected.

StudScan and DeepScan Modes

Use StudScan Mode to find the center, edges, and direction of wood or metal studs up to 0.75 in. (19 mm) deep.

For best results, always start in StudScan Mode when looking for studs.

If StudScan Mode provides irregular readings, or the Signal Strength Indicator is weak, the studs might be behind deeper than 0.75 in. (19 mm). Slide the Mode Selector Switch to DeepScan Mode. This doubles the scanning depth to 1.5 in. (38 mm) deep and allows for increased accuracy on deeper targets.

Before scanning, hold the A250 flat against wall and press the Power Button to calibrate. Be sure not to move the scanner while calibrating. After a short beep sounds confirming calibration is complete, continue pressing the Power Button and slide the scanner slowly against the surface.

When the A250 finds the edges and center of a stud, 'Edge' and 'Center' displays respectively, indicating you have found your target. When the stud's center is located, the SpotLite Pointer also illuminates and a short beep sounds.

The center of the stud is the stud's most secure location. It is critical to drill in the center of a stud when mounting heavy objects.

Note: WireWarning Detection works in both StudScan and DeepScan Modes. The Live AC Icon will appear when live, unshielded wires are detected.

Auto Correcting Technology (ACT)

Automatically Have Common Errors Corrected.

This feature enables the scanner to automatically adjust for common calibration errors. It checks calibration 10 times per second and automatically recalibrates when/if needed. If scanning begins directly over a stud, the tool will transparently recalibrate, so you don't have to, and will find that stud when you scan back over it.

This recalibration is usually transparent and no indication is made. If an arrow icon illuminates, the scanner was calibrated near or over a stud and then moved away. The arrow indicates the direction of the missed stud.

Frequently Asked Questions

Question: Does the MultiScanner A250 include a battery?

Answer: No. Zircon stud finders and detectors, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, a brand-new, recently purchased 9V alkaline battery with an extended expiration date, is not included but is required to properly power the A250.

Question: I inserted a 9V battery, but the scanner doesn't turn on or is giving me strange readings. Is my scanner broken?

Answer: Please be sure to use a fresh, brand new 9V alkaline battery with an extended expiration date. Batteries that may work in a smoke detector or remote control may not have adequate voltage to power the sensing technology in MultiScanners.

Question: Does this scanner need to be calibrated?

Answer: Yes, as with all Zircon scanners, the MultiScanner A250 needs to calibrate to the surface before scanning. Calibrating the scanner on an empty wall gives the device a chance to measure the wall thickness and material density, as well as register factors like humidity, temperature, and even the minor electric readings from your hand, which all have an impact on the readings from the wall. Calibrating is easy and just takes a second. To calibrate, simply place the unit flat against the surface to be scanned and press the Power Button. When powering the A250 on, all the icons on the screen and the SpotLite Pointing System will briefly flash and the scanner will beep. After this occurs, the screen will then clear and, depending on the selected mode, the words 'StudScan', 'DeepScan', 'Metal' or the Live AC Icon will remain, indicating that calibration has occurred and the scanner is ready to begin scanning. It is important not to move the scanner or begin scanning until the calibration process has taken place for the most accurate results.

Question: What does 'Center Finding' mean?

Answer: Center Finding stud finders locate both the edges and the center of wood and metal studs and joists in one step. 'Edge Finding' stud finders, on the other hand, only find the edges of studs, so you must determine the center. Finding the center of the stud to mount heavy objects is critical as the stud's center is the most secure location of the stud.

Question: What is DeepScan Mode?

Answer: Unlike StudScan Mode which scans through one layer of drywall up to 0.75 in. thick (19 mm), DeepScan Mode scans through 2 layers of drywall up to 1.5 in. (38 mm) deep. DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling. Extra layers in a wall can make it difficult to find studs in regular StudScan Mode. To minimize false positives and/or finding other objects further behind the wall that may not be a stud, always start your scan in StudScan Mode first.

Question: How can I be certain the objects found behind my wall are studs in DeepScan Mode?

Answer: DeepScan Mode has increased sensitivity so you may have located something other than a stud. Studs are equally spaced to either side (12, 16, or 24 in. apart) and typically run from floor to ceiling. To better confirm that what you found is a stud, check for other studs equally spaced to either side and for the same stud at several heights directly above and below the first stud indication. A stud reading would also measure approximately 1.5 in. (38 mm) apart from each edge. Anything larger or smaller may not be a stud if not near a door or window.

Question: Will this MultiScanner A250 locate metal studs?

Answer: Yes, the A250 will locate metal studs in StudScan, DeepScan, and Metal Scan Modes. Since stud finders are looking for a change in density behind drywall, not a particular material, in StudScan, DeepScan, and Metal Scan Modes, the detector will react to metal studs the same as it would for wooden studs. The A250 will locate wood and metal studs up to 0.75 in. (19 mm) deep while DeepScan Mode locates targets up to 1.5 in. (38 mm) deep. In Metal Scan Mode, the detector will only detect metal studs, in addition to any other metal, within its specified scan depth and range.

Question: Why does the scanner beep and the lights flash when scanning for a stud?

Answer: The scanner could've been calibrated over a stud, calibrated on a dense part of the wall, or the back of the unit may have slightly lifted or tilted during the scan. Move the MultiScanner A250 over a couple of inches to the left or right, re-calibrate, and start your scan again.

Question: What is WireWarning Detection?

Answer: WireWarning Detection is a feature that is always on while you are scanning in StudScan, DeepScan, and Metal Scan Modes to alert you to the presence of live, unshielded electrical AC wires up to 2 in. (50 mm) deep. As you approach an area with live AC voltage, the Live AC Icon will display on the LCD screen. This is the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, the Live AC Icon will flash. Please turn off the electricity and use extreme caution in areas where live ac voltage is detected before nailing or drilling.

Question: What is the difference between AC Scan and WireWarning Detection?

Answer: Zircon MultiScanner models have a feature called WireWarning Detection that alerts you when the scanner is in the vicinity of live AC voltage while you are actively scanning for studs or metal. WireWarning Detection continuously detects hot, unshielded electrical wires up to 2 in. (50 mm) in StudScan, DeepScan, and Metal Scan.

AC Scan, however, is a dedicated scan mode in which the user interface displays bars on the LCD screen that indicate when the scanner is moving towards the source of the voltage or away. Both WireWarning Detection and AC Scan Mode may indicate over a smaller or larger zone around the wire depending on conditions. Both features allow the user to interactively calibrate the sensitivity to AC voltage. If the unit indicates over a large area the user can re-calibrate the unit closer to the source of AC in order to reduce sensitivity so the unit will indicate AC over a smaller zone around the wire.

Question: What can this product do in terms of wire tracing?

Answer: Zircon scanners with AC Scan Mode are not full featured wire tracers. They will however, enable you to map a section of a wall. AC Scan Mode can assist you in locating the route a wire takes through sections of the wall.

Question: Why does the area of voltage appear much larger than an actual wire?

Answer: Static charge may develop on drywall, spreading voltage detection as much as 12 in. (30 cm) laterally from each side of an actual wire. To narrow detection, turn the scanner off and on again at the edge of where the wire was first detected and repeat the scan.

Question: I suspect electrical wires in a certain area when I scan, but why am I not detecting any?

Answer: Wires may be shielded in metal conduit or behind a metallic wall covering. It could also be that the wire is deeper than 2 in. or that the wire may not be live (hot). Try Metal Scan Mode to see if you can find metal, wire, or metal conduit. Always exercise extreme caution when working near electricity.

Question: Does the A250 work on wood paneling and other wood surfaces?

Answer: The A250 is optimized to scan through standard interior sheetrock / drywall (gypsum) construction. This scanner will work on wood, plywood, wood paneling and particle board up to 1.5 in. (38 mm) thick when in DeepScan Mode.

Question: Will the A250 work on textured wall surfaces, acoustic ceilings, or wallpaper?

Answer: Yes, the A250 will work on textured surfaces and dried wallpaper as long as it does not contain any metallic foil or fibers. For highly textured walls or acoustic ceilings, place or tape a thin piece of cardboard onto the surface to be scanned. Recalibrate and scan over the cardboard in DeepScan Mode.

Question: Can I use this scanner to find studs behind carpet?

Answer: No. Zircon scanners are designed for hollow interior walls. They will generally work well to find studs or joists through a plywood subfloor, after the carpeting/flooring has been removed.

Question: Will the A250 work on ceramic tile?

Answer: While the MultiScanner A250 may be able to scan through ceramic tile in DeepScan Mode to locate studs, the many variable layers behind tiled surfaces make it one of the more difficult scanning environments. To find studs through ceramic tile, we suggest using Metal Scan Mode to find the nails or screw heads attaching the backing surface to the studs.

Question: Does this MultiScanner work on lath and plaster?

Answer: Yes. Using Metal Scan Mode, you can identify a stud behind the lath and plaster wall by locating the pattern of nail or screw heads attaching the wood lath to the studs. The nails or screws should be found in a column when scanning for metal. However, if the plaster has metal mesh reinforcement, the MultiScanner A250 will not be able to detect an accurate pattern of nail heads through that material.

Question: What does the Signal Strength Indicator do?

Answer: To help you filter out the target from potential decoys that would give the A250 a false reading, the Signal Strength Indicator gives a reading of the strength, or the certainty, of the returning signal from the wall. Three bars (the highest level) indicates an obvious result behind a normal wall, while two bars (or below) indicates that while the device has found something, it may either be a smaller object than your target, or the target is behind an extra thick wall. Since every wall is built differently, and since any wall can have pipes, wires, or other objects behind it that can return a result, you can use the Signal Strength Indicator to 'map out' your wall to determine the target from the other objects.

Question: Can I use this scanner to scan the outside wall of my house?

Answer: No. Zircon MultiScanners are designed and recommended for interior use only.

Question: I'm planning to mount my new flat screen TV to the wall. Will this scanner help me?

Answer: Yes. The A250 is ideal for basic home or office projects. The center-finding technology allows you to easily find and mark the center of the stud for secure mounting of TV's and AV equipment, closet or garage shelving, heavy mirrors, light fixtures, coat racks and more.

Question: Is the scanner waterproof?

Answer: No. The MultiScanner A250 is splash and water resistant, but not waterproof.

Question: What is the difference between magnetic and electronic stud finders?

Answer: Magnetic stud finders are simply magnets that look for anything magnetic behind a wall. Typically, they are advertised to find screws or nails that hold the wall surface to the studs. However, nails often times are not placed in the center of studs, making it difficult to determine where the stud's center is or how wide the stud is.

Electronic stud finders, such as the A250, on the other hand, operate by detecting density changes behind a surface (like a wall) and will clearly and precisely indicate the edges and center of a stud. The center of a stud is the most secure location when mounting anything heavy. For applications like mapping out floor joists, electronic stud finders have an advantage over magnets because they are not attracted to nails holding floor boards to a subfloor, as well as nails in joists.

Question: Does the MultiScanner A250 come with a warranty?

Answer: The MultiScanner A250 includes limited one year warranty when fulfilled by and shipped from Amazon.

Product description

The Zircon MetalliScanner m40 electronic metal scanner quickly and easily detects metal in lath and plaster, wood, drywall, paneling, tile, stucco, plaster, concrete and other non-metallic surfaces. This metal detector locates ferrous (magnetic) metal up to 4 inches (100 mm) deep and non-ferrous (non-magnetic) metal up to 2 inches (50 mm) deep. The Zircon m40 has two scanning positions, Wide Scan and Pinpoint Scan. To get started, install the included 9V alkaline battery. Hold the tool in the air away from any metal but make sure the blue sensor is parallel to the surface being scanned. Press and hold the Power Button to calibrate the unit. Once you hear a beep and see the green "Ready" LED illuminated, calibration is complete. Continue to hold the Power Button as you slowly slide the tool across the surface. As the MetalliScanner approaches a metal object, the red LEDs progressively light from the bottom up in both scanning modes.

Zircon MetalliScanner m40

The MetalliScanner m40 quickly and easily detects metal in wood, drywall, paneling, tile, stucco, plaster, concrete, and other non-metallic surfaces. It locates ferrous (magnetic) metal up to 4 inches (10 cm) deep and non-ferrous (non-magnetic) metal up to 2 inches (5 cm) deep. The MetalliScanner m40 finds plumbing, ductwork, rebar, nails, and screws in walls, floors, and ceilings, and is great for scanning reclaimed lumber for hidden metal.

m40 Functions:

- Detects ferrous and non-ferrous metals in most non-metallic surfaces.

- Finds the pattern of nails to detect studs.

- LED arrays indicate signal strength.

- Blue coil and audio tone indicate when metal target is located.

- PinPoint Scan locates small objects, including screws and nails.

- Wide Scan detects metal in walls or concrete.

PinPoint Scan

Use the m40's PinPoint Scan position to locate small metal targets such as nails and refine your search results.

How to Use:

As the m40 approaches a metal object, the red LEDs progressively light from the bottom up. The top lighted blue coil and an audio tone indicate the strongest signal when a metal target is located.

Calibrate away from any metal for maximum sensitivity. Recalibrating closer to the target decreases sensitivity to find the precise location of metal.

Wide Scan

Use the m40's Wide Scan to quickly find approximate locations of metal in walls and/or concrete.

Use the m40 in Wide Scan position just as you would in PinPoint Scan position.

Scanning through Lath and Plaster

The m40 solves the difficult problem of finding studs in lath and plaster walls that do not contain metal mesh by finding the pattern of nails that attach the wood lath to the studs.

The m40 scans through lath and plaster in both PinPoint Scan and Wide Scan positions.

Key to Success is the Battery

A fully charged 9V battery is required to steadily power the integrated LCD screen in Zircon tools. Please note that, like a cell phone or any personal electronic device, the 9V batteries needed to power Zircon tools can lose power even when sitting idle. The installation of a fresh battery, with an extended expiration date, typically resolves 99% of problems seen by Zircon Customer Support.

User questions & answers

Question:	Does this work to detect studs in walls with spray foam insulation
Answer:	Hi. Zircon stud finders and multiscanners are optimized for standard interior drywall construction. Other interior surfaces can be penetrated with our scanners, but brick, slate, and rock type material are too dense. Thanks.
Question:	How is "wirewarning detection" different than "ac scan mode"? both say they find, "live, unshielded electrical ac wires up to 2 inches (50 cm) deep
Answer:	Hi. The packaging you received your A250 in is called "FFP". That stands for frustration free packaging. The other type would be the standard plastic "clamshell". Most folks prefer the FFP. I believe you can purchase the stud finder products either way from Amazon. Thanks.
Question:	does this stud finder come packaged, mine did not is that normal
Answer:	Hello Chris. Due to the variables in building techniques, materials and densities in exterior construction Zircon stud sensors are recommended for interior use only. Our stud sensors locate studs by finding changes in density and the density of the material you mention would not allow the A250 to calibrate properly and as such would prevent it from scanning for the studs. Thank you.
Question:	Will it work with brick walls
Answer:	Hello. The stud finder A250 does not come with a case. Thank you.

Product features

Zircon MultiScanner A200

The MS A200 is a handheld tool dedicated to quickly and efficiently find studs, detect metal and alert you of live AC wiring. The A200 comes equipped with 3 scanning modes: StudScan, DeepScan and Metal Scan.

3 Mode Multifunctional Wall Scanner with Backlit Display

The Zircon MultiScanner A200 makes scanning easy with its newly designed ergonomic grip. The scanner's StudScan finds shallower wood or metal studs up to 0.75 in. (19 mm) deep while DeepScan doubles the scanning depth to 1.5 in. (38 mm).

Metal Scan locates both non-ferrous (non-magnetic) metal, such as copper pipe, and ferrous (magnetic) metal, such as rebar. The A200 is able to detect non-ferrous metal up to 1.5 in. (38 mm) deep, and ferrous metal up to 3 in. (75 mm) deep.

The A200 also includes WireWarning Detection that automatically operates in StudScan, DeepScan and Metal Scan Modes. This safety feature alerts you to the presence of live, unshielded electrical AC wires while scanning for studs and metal.

Before use, always be sure to install a brand new 9V alkaline battery. Zircon stud finders, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, brand-new, recently purchased alkaline batteries with an extended expiration date, are strongly recommended for use in these tools.

StudScan and DeepScan

Use StudScan Mode to find the center, edges, and direction of wood or metal studs up to 0.75 in. (19 mm) deep.

For best results, always start in StudScan Mode when looking for studs.

If StudScan Mode provides irregular readings, or the Signal Strength Indicator is weak, the studs might be behind deeper than 0.75 in. (19 mm). Slide the Mode Selector Switch to DeepScan Mode. This doubles the scanning depth to 1.5 in. (38 mm) deep and allows for increased accuracy on deeper targets.

Before scanning, hold the A200 flat against wall and press the Power Button to calibrate. Be sure not to move the scanner while calibrating. After a short beep sounds confirming calibration is complete, continue pressing the Power Button and slide the scanner slowly against the surface.

When the A200 finds the edges and center of a stud, 'Edge' and 'Center' displays respectively, indicating you have found your target. When the stud's center is located, the SpotLite Pointer also illuminates and a short beep sounds.

The center of the stud is the stud's most secure location. It is critical to drill in the center of a stud when mounting heavy objects.

Note: WireWarning Detection works in both StudScan and DeepScan Modes. The WireWarning Detection Icon will appear when live, unshielded wires are detected.

Metal Scan

Detect Both Ferrous and Non-Ferrous Metal.

Use Metal Scan Mode to locate and avoid hazards, such as pipes, behind walls and determine if a stud is wood or metal.

Metal Scan Mode detects non-ferrous metal, such as copper pipe, up to 1.5 in. (38 mm) deep, and ferrous metal, such as rebar, up to 3 in. (75 mm) deep.

To use, be sure to first calibrate the A200. For maximum sensitivity, press and hold the Power Button while holding the scanner away from the surface. Once a short beep sounds confirming calibration is complete, place against the surface to be scanned. Be sure to continue to hold the Power Button.

Just like in AC Scan Mode, slowly slide the scanner across the surface and mark the spot where the most display bars peak. Continue scanning until the bars reduce and reverse the direction.

The midpoint between the two marks is the location of the metal target.

Note: WireWarning Detection works in Metal Scan Mode. The WireWarning Detection Icon will appear when live, unshielded wires are detected.

WireWarning Detection

Be Alerted of Live Electrical Wiring in all Modes.

WireWarning Detection is a feature that is always on while scanning in StudScan, DeepScan, and Metal Scan Modes.

It alerts you to the presence of live, unshielded electrical AC wires up to 2 inches (50 cm) deep.

As you approach an area with live AC voltage, a lightning bolt icon will display on the LCD screen. This the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, the WireWarning Detection Icon will flash.

Note: Please turn off the electricity and use extreme caution in areas where live AC voltage is detected before nailing or drilling.

Auto Correcting Technology (ACT)

Automatically Have Common Errors Corrected.

This feature enables the scanner to automatically adjust for common calibration errors. It checks calibration 10 times per second and automatically recalibrates when/if needed. If scanning begins directly over a stud, the tool will transparently recalibrate, so you don't have to, and will find that stud when you scan back over it.

This recalibration is usually transparent and no indication is made. If an arrow icon illuminates, the scanner was calibrated near or over a stud and then moved away. The arrow indicates the direction of the missed stud.

Frequently Asked Questions

Question: Does the MultiScanner A200 include a battery?

Answer: No. Zircon stud finders and detectors, particularly those with LCD screens, require and consume a great deal of current from batteries. For optimal performance, a brand-new, recently purchased 9V alkaline battery with an extended expiration date, is not included but is required to properly power the A200.

Question: I inserted a 9V battery, but the scanner doesn't turn on or is giving me strange readings. Is my scanner broken?

Answer: Please be sure to use a fresh, brand new 9V alkaline battery with an extended expiration date. Batteries that may work in a smoke detector or remote control may not have adequate voltage to power the sensing technology in MultiScanners.

Question: Does this scanner need to be calibrated?

Answer: Yes, as with all Zircon scanners, the MultiScanner A200 needs to calibrate to the surface before scanning. Calibrating the scanner on an empty wall gives the device a chance to measure the wall thickness and material density, as well as register factors like humidity, temperature, and even the minor electric readings from your hand, which all have an impact on the readings from the wall. Calibrating is easy and just takes a second. To calibrate, simply place the unit flat against the surface to be scanned and press the Power Button. When powering the A200 on, all the icons on the screen and the SpotLite Pointing System will briefly flash and the scanner will beep. After this occurs, the screen will then clear and, depending on the selected mode, the words 'StudScan', 'DeepScan' or 'Metal' will remain, indicating that calibration has occurred and the scanner is ready to begin scanning. It is important not to move the scanner or begin scanning until the calibration process has taken place for the most accurate results.

Question: What does 'Center Finding' mean?

Answer: Center Finding stud finders locate both the edges and the center of wood and metal studs and joists in one step. 'Edge Finding' stud finders, on the other hand, only find the edges of studs, so you must determine the center. Finding the center of the stud to mount heavy objects is critical as the stud's center is the most secure location of the stud.

Question: What is DeepScan Mode?

Answer: Unlike StudScan Mode, which scans through one layer of drywall up to 0.75 in. thick (19 mm), DeepScan Mode scans through 2 layers of drywall up to 1.5 in. (38 mm) deep. DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling. Extra layers in a wall can make it difficult to find studs in regular StudScan Mode. To minimize false positives and/or finding other objects further behind the wall that may not be a stud, always start your scan in StudScan Mode first.

Question: How can I be certain the objects found behind my wall are studs in DeepScan Mode?

Answer: DeepScan Mode has increased sensitivity so you may have located something other than a stud. Studs are equally spaced to either side (12, 16, or 24 in. apart) and typically run from floor to ceiling. To better confirm that what you found is a stud, check for other studs equally spaced to either side and for the same stud at several heights directly above and below the first stud indication. A stud reading would also measure approximately 1.5 in. (38 mm) apart from each edge. Anything larger or smaller may not be a stud if not near a door or window.

Question: Will this MultiScanner A200 locate metal studs?

Answer: Yes, the A200 will locate metal studs in StudScan, DeepScan, and Metal Scan Modes. Since stud finders are looking for a change in density behind drywall, not a particular material, in StudScan, DeepScan, and Metal Scan Modes, the detector will react to metal studs the same as it would for wooden studs. The A200 will locate wood and metal studs up to 0.75 in. (19 mm) deep while DeepScan Mode locates targets up to 1.5 in. (38 mm) deep. In Metal Scan Mode, the detector will only detect metal studs, in addition to any other metal, within its specified scan depth and range.

Question: Why does the scanner beep and the lights flash when scanning for a stud?

Answer: The scanner could've been calibrated over a stud, calibrated on a dense part of the wall, or the back of the unit may have slightly lifted or tilted during the scan. Move the MultiScanner A200 over a couple of inches to the left or right, re-calibrate, and start your scan again.

Question: What is WireWarning Detection?

Answer: WireWarning Detection is a feature that is always on while you are scanning in StudScan, DeepScan, and Metal Scan Modes to alert you to the presence of live, unshielded electrical AC wires up to 2 in. (50 mm) deep. As you approach an area with live AC voltage, a lightning bolt icon will display on the LCD screen. This is the WireWarning Detection Icon. If your scan directly starts over an area with live AC voltage, this icon will flash. Please turn off the electricity and use extreme caution in areas where live ac voltage is detected before nailing or drilling.

Question: Why does the area of voltage appear much larger than an actual wire?

Answer: Static charge may develop on drywall, spreading voltage detection as much as 12 in. (30 cm) laterally from each side of an actual wire. To narrow detection, turn the scanner off and on again at the edge of where the wire was first detected and repeat the scan.

Question: I suspect electrical wires in a certain area when I scan, but why am I not detecting any?

Answer: Wires may be shielded in metal conduit or behind a metallic wall covering. It could also be that the wire is deeper than 2 in. or that the wire may not be live (hot). Try Metal Scan Mode to see if you can find metal, wire, or metal conduit. Always exercise extreme caution when working near electricity.

Question: Does the A200 work on wood paneling and other wood surfaces?

Answer: The A200 is optimized to scan through standard interior sheetrock / drywall (gypsum) construction. This scanner will work on wood, plywood, wood paneling and particle board up to 1.5 in. (38 mm) thick when in DeepScan Mode.

Question: Will the A200 work on textured wall surfaces, acoustic ceilings, or wallpaper?

Answer: Yes, the A200 will work on textured surfaces and dried wallpaper as long as it does not contain any metallic foil or fibers. For highly textured walls or acoustic ceilings, place or tape a thin piece of cardboard onto the surface to be scanned. Recalibrate and scan over the cardboard in DeepScan Mode.

Question: Can I use this scanner to find studs behind carpet?

Answer: No. Zircon scanners are designed for hollow interior walls. They will generally work well to find studs or joists through a plywood subfloor, after the carpeting/flooring has been removed.

Question: Will the A200 work on ceramic tile?

Answer: While the MultiScanner A200 may be able to scan through ceramic tile in DeepScan mode to locate studs, the many variable layers behind tiled surfaces make it one of the more difficult scanning environments. To find studs through ceramic tile, we suggest using Metal Scan Mode to find the nails or screw heads attaching the backing surface to the studs.

Question: Does this MultiScanner work on lath and plaster?

Answer: Yes. Using Metal Scan Mode, you can identify a stud behind the lath and plaster wall by locating the pattern of nail or screw heads attaching the wood lath to the studs. The nails or screws should be found in a column when scanning for metal. However, if the plaster has metal mesh reinforcement, the MultiScanner A200 will not be able to detect an accurate pattern of nail heads through that material.

Question: What does the Signal Strength Indicator do?

Answer: To help you filter out the target from potential decoys that would give the A200 a false reading, the Signal Strength Indicator gives a reading of the strength, or the certainty, of the returning signal from the wall. Three bars (the highest level) indicates an obvious result behind a normal wall, while two bars (or below) indicates that while the device has found something, it may either be a smaller object than your target, or the target is behind an extra thick wall. Since every wall is built differently, and since any wall can have pipes, wires, or other objects behind it that can return a result, you can use the Signal Strength Indicator to 'map out' your wall to determine the target from the other objects.

Question: Can I use this scanner to scan the outside wall of my house?

Answer: No. Zircon MultiScanners are designed and recommended for interior use only.

Question: I'm planning to mount my new flat screen TV to the wall. Will this scanner help me?

Answer: Yes. The A200 is ideal for basic home or office projects. The center-finding technology allows you to easily find and mark the center of the stud for secure mounting of TV's and AV equipment, closet or garage shelving, heavy mirrors, light fixtures, coat racks and more.

Question: Is the scanner waterproof?

Answer: No. The MultiScanner A200 is splash and water resistant, but not waterproof.

Question: What is the difference between magnetic and electronic stud finders?

Answer: Magnetic stud finders are simply magnets that look for anything magnetic behind a wall. Typically, they are advertised to find screws or nails that hold the wall surface to the studs. However, nails often times are not placed in the center of studs, making it difficult to determine where the stud's center is or how wide the stud is.

Electronic stud finders, such as the A200, on the other hand, operate by detecting density changes behind a surface (like a wall) and will clearly and precisely indicate the edges and center of a stud. The center of a stud is the most secure location when mounting anything heavy. For applications like mapping out floor joists, electronic stud finders have an advantage over magnets because they are not attracted to nails holding floor boards to a subfloor, as well as nails in joists.

Question: Does the MultiScanner A200 come with a warranty?

Answer: The MultiScanner A200 includes limited one year warranty when fulfilled by and shipped from Amazon.

Question: Where can I get help using my MultiScanner A200?

User questions & answers

Question:	I have the old style plaster walls that's super think. Will this still work
Answer:	I believe it is likely to work.
Question:	Will it work through wood paneling
Answer:	Hi. Thank for your question. WireWarning is included on most Zircon stud finders and on all Mutiscanner tools. You can think of it as a safety feature. It will "warn" you when you are in proximity of live AC behind your wall. Depending where you calibrate the scanner on the wall, it's usually within a couple feet / two inches depth. WireWarning is not designed to trace live AC, or point out exactly where the line is. AC scan will allow you to trace where the wire source is and the direction of the line. If you need to know where the wire / line is and where it's going, that's when you need the AC scan mode. I hope this information is helpful. Thank you.
Question:	Can this scan plastic pipe behind the concrete
Answer:	Sounds like bulk or non-retail packaging. Likely ok.
Question:	I have sheet rock mounted on furring strips against a concrete block walls. Will this stud finder Zircon 70 locate the furring strips
Answer:	Hi. Zircon stud finders and multiscanners are optimized for standard interior drywall construction. Other interior surfaces can be penetrated with our scanners, but brick, slate, and rock type material are too dense. Thanks.

• WireWarning detection indicates the presence of live, unshielded electrical wire up to 2 inches (51 mm) deep in stud and metal scanning modes. Most wires in homes are run along wall studs, causing potential safety hazards.
• ACT (Auto Correcting Technology) automatically corrects common user errors, such as when scanning begins over a stud. The tool constantly scans its surroundings and recalibrates itself if necessary.
• An ultra-bright LCD screen indicates direction, edges and center of studs. Makes the screen easier to see in low-light situations.
• The display screen, SpotLite Pointing System, and audio tone all indicate the location of the target.
• A signal strength indicator lets you distinguish between shallow and deep targets. Weak signal strength can also imply other non-stud objects, like wires and pipes.

The i520 is a perfect choice for serious users, such as home improvement hobbyists and professional contractors. Not sure if the i520 is what you need? See the grid below to decide which center-finding tool is right for you.

User questions & answers

Question:	will this find some 14 romax electric wire behind frywall
Answer:	Hi LeeAnn. The short answer is, no it won't. Stud scanners are not recommended for plaster construction in general. You need a metal scanner tool such as a Zircon i520 or M40. Please check out this video : https://www.youtube.com/watch?v=rY2Ds086atY. I hope this info help you. Thanks.
Question:	Will this work to locate live BX electrical wire embedded in masonry walls behind plaster? Has anybody had similar situation
Answer:	Hello. The StudSensor™ 70 will work through wood paneling as long as the total scanning depth from the wood paneling to the stud is not over 1 and ½ inches. Thank you.
Question:	can i find studs behind plaster walls and electic wiring
Answer:	Hello. No, the SS70 cannot find plastic pipe behind concrete. Thank you.
Question:	What kind of battery does it use
Answer:	Hi. The stud finder will easily penetrate the 1/2" drywall. If the Drywall is nailed flush to the furring strips, that is a density change that the scanner would pick up and indicate. I hope this answers your question. Thanks.

Product features

Zircon StudSensor e50 Electronic Stud Finder

The StudSensor e50 quickly and easily locates the edges of wood and metal studs and joists behind walls, floors, and ceilings. Two scanning modes allow you to scan more surfaces in your home than normal stud finders.

StudSensor e50 Functions:

- Easy-to-read LCD display indicates stud edges.

- SpotLite Pointer shines an arrow-shaped light on the wall marking the target.

- Ergonomic grip design allows a comfortable hold on the tool in either hand, at any angle.

- Wire Warning detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep.

- Zircon's patented 'over-the-stud' indication alerts the user to start scanning in a new location should scanning begin over a stud.

StudScan

Use this mode to find the edges of wood or metal studs up to 3/4 inches (19 millimeters) deep. For best results, always start in this mode when looking for studs.

Note: WireWarning detection works in both StudScan and DeepScan modes. The indicator flashes on the screen when detecting a live, unshielded wire.

DeepScan

If StudScan mode provides irregular readings or the Signal Strength indicator is weak, the studs might be behind more than ¾ inches (19 millimeters) of drywall. Slide the mode selector over one notch to switch to DeepScan mode. This doubles the scanning depth to 1½ inches (38 millimeters) deep and allows for increased accuracy on deeper targets.

Note: WireWarning detection works in both StudScan and DeepScan modes. The indicator flashes on the screen when detecting a live, unshielded wire.

WireWarning Detection

WireWarning detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep. This feature works in both StudScan and DeepScan modes.

The Key to Success is in the Battery

A new, fully charged 9V battery is required to steadily power the integrated LCD screen in Zircon tools. Please note that, like a cell phone or any personal electronic device, the 9V batteries needed to power Zircon tools can lose power even when sitting idle. The installation of a fresh battery, with an extended expiration date, typically resolves 99% of problems seen by Zircon Customer Support.
