User questions & answers

Question:	does it detect floor studs under carpet and padding
Answer:	Scan goes 1.5 inches on deep scan most subfloors are 1 inch plus carpet and pad.....my guess is no. Im guessing you need to add floor outlet. In that case look for hvac vents in floor to show orientation of floor joices. Best thing ive done is drill 1/8 inch hole and put long steel wire down through insulation then go in crawl to see if in between floor joices. Ive seen some electricians just drill it where homeowner wants floor outlet and if they hit joice they just drilled it out and installed floorbox to hide mistake. Most stud finders dont do good on flooring
Question:	Does it work on metal studs
Answer:	Yes.
Question:	Our walls are 3/4 inch tongue and groove. Will this be able to detect through that
Answer:	The ProSensor 710+ should detect through wood tongue and groove walling material.
Question:	will it detect and show studs behind plaster and lath
Answer:	This unit can detect studs through lath and plaster, but it is not guaranteed as it is on drywall. Because lath and plaster usually is usually thicker and less consistent, it could lead to some inconsistent readings. The multiple sensors and deep sensing capabilities on this stud finder give it a better chance on lath and plaster, but it cannot be guaranteed.

User questions & answers

Question:	how well over thick second floor carpet
Answer:	the studpop doesn't respond to electricity at all. But since the studpop is looking for actual metal fasteners, when it does find one, it's a good bet that it's not in a wire.
Question:	Will this detect studs behind plaster and will it detect wires
Answer:	3/4" might be pushing it but that also seems awful thick for plaster over lath. IT always works for me on L & P
Question:	can this alert you to AC runs in t he wall
Answer:	The studpop was designed to work on any kind of wall. Sheetrock, plaster, lath and plaster, tile. That's the guarantee. If it doesn't appear to be working then it's either defective or you're not using it right. In either case contact the company and they'll figure it out. Being a new company with a very new product, they are very eager to please ; )
Question:	Can you find studs thru exterior stucco or wood siding? Thanks
Answer:	We don't have popcorn textured ceilings. I think ours are called slap brush, and it definitely does stay on them (I just tried it tonight to find out).

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.

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?

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 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 StudSensor A150 locate metal studs?

Answer: Yes, the A150 will locate metal studs in StudScan and DeepScan 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 A150 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 A150 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 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 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 A150 work on wood paneling and other wood surfaces?

Answer: The A150 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 A150 work on textured wall surfaces, acoustic ceilings, or wallpaper?

Answer: Yes, the A150 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 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 A150 work on ceramic tile?

Answer: While the StudSensor A150 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: 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.

Question: Is the tool waterproof?

Answer: No. The StudSensor A150 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 A150, 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 A150 come with a warranty?

Answer: The StudSensor A150 includes limited one year warranty when fulfilled by and shipped from Amazon.

Question: Where can I get help using my StudSensor A150?

User questions & answers

Question:	I need to find ceiling joists under a layer of sheetrock and 1" of board insulation. Can it sense this deep
Answer:	This tape is NOT 300 inches long. 300 inches is 25 feet. 25 feet is NOT 16 feet, and the description clearly states this tape is 16 feet long.
Question:	Will this work on extirior stucco walls
Answer:	Yes, it is.
Question:	On the back it says, restart unit to re-calibrate. But this model, just has a single button. How do you restart this unit
Answer:	This is actually on purpose. The tip should be able to slide the length of its own thickness so that you can take an inside measurement (e.g. tip pressed against floor, tape stretched up to window sill) or outside (e.g. tip hooked around one edge of a counter, tape stretched to the opposite edge). Not a huge difference for most common uses, but if accuracy matters down to 1/16" then a sliding tip allows the measurement to be accurate when done either way.
Question:	Will this work on a ceiling? It's a rough surface
Answer:	Yes it did, very well actually. I can't comment on how long or how well the autolock would hold up because the tape bent pretty bad the first time I allowed it to retract at full speed. I would recommend a higher quality tape unless you're extremely careful.

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.

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.

Product features

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?

Stud Scan Detection

Deep Scan 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. 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.

Metal Scan Detection

Tavool wall canner will locate metal studs in StudScan, DeepScan, and Metal Scan Modes. Since Tavool 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.

After you detect the center of a object, Please Use Metal Scan to determine if the previous reading in Stud scan was a wood stud, metal stud, or pipe.

Live AC Wire Detection

AC Wire detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep. In all modes, this wall scanner always detect and indicate the Live AC Wire.

Note: AC Wire Detection works in both StudScan / DeepScan / MetalScan Modes. The AC Wire Detection Icon will flash when live, unshielded wires are detected.

Step 1:Calibrate the tool before every scan

After choose the mode, press and hold the scan button( on the side of the tool) to calibrate this tool. Wait for the reducing bars disappeared and beep to confirm calibration has completed.

In stud/deep mode, put it on the wall where you want to detect to calibrate it ;In AC/Metal mode, put it in the air to calibrate it.

Step 2: Scan the wall

Hold down the button, then move the stud finder along the wall slowly, if shake or lift the scanner accidently, the device needs to be re-calibrate.

The narrow on the screen togather with the beep signal alter, guides you to find the location of the stud.

User questions & answers

Question:	Can anyone compare this to the 4-in-1 version? is it just the moisture meter? it looks like maybe the screen is a little different. better? worse
Answer:	I would think that it would. I would first take one sickness of newspaper to the area to be scanned to have a smooth surface to slide the stud Sensor on. Then, double-click for deep sensing and search for studs.
Question:	Can it find a live wire in wood mode
Answer:	Hi. Powering the unit on is calibrating it. As soon as the "trucal" green LED is lit, the unit is calibrated and ready to scan. Thanks.
Question:	Where can I download a user manual
Answer:	Had no idea, so I just tried it. Sure does. It even found the electrical going to the ceiling fan.
Question:	Is detection reliable through concrete walls
Answer:	Hi Shawna. The Zircon StudSensor Pro SL-AC stud finder requires one brand new 9 volt alkaline battery. For optimal performance, please use a battery with an extended expiration date of at least three years beyond the current date. Thank you.

5 Scanning Modes Maximum Scanning Depth

The Tacklife stud finder DMS05 has 5 ways to help you detect.

Ferrous metals: 4-3/4˝ / 120mm

Non-ferrous metals(Copper): 3-1/8˝ / 80mm

Copper conductors (live AC):2˝ / 50mm

Wood exact mode: 3/4˝ / 20mm

Wood deep mode: 1-1/2˝ / 38mm

Moisture test pins length: 0.3˝ / 8mm

Step One

• Hold the tool straight up and down, parallel to the studs, and do not rotate the tool.
• Keep tool flat against the wall and do not rock, tilt, or press hard when slowly sliding across the surface being scanned.

Step Two

• Move the detector uniformly over the surface without lifting it off or changing the applied pressure (During the scan, the detector must cling to the wall).
• As the detector begin to approach a stud, the scale h will increase, and the percentage of intensity will also increase, the yellow light will be on.

Step Three

• When the red light is on, the buzzer will sound, the scale and the percentage will increase to the max, the center of stud is located. At this time, make a mark below the top groove of the detector.

1.Ready for metal detecting

• Short press the button on the right side with " 工" shown on the display to enter metal detecting mode (default mode);
• When the detector is far away from the metal, there's with green light on and the signal strength is empty in 0%;
• Move the tool uniformly across the surface

2.Sign the first point

• When the light turns into yellow and the detecting signal strengthen, the detector is close to the metal with a steady tone sound;
• Sign the first point for recording to remind yourself

3.Sign the second point

• As the light turns from yellow/ red to yellow and the signal strength percentage decrease to like the result as step 2，the buzzer will stop sounding;
• Sign the second point for recording as the same as before

4.Get exact position

• Combine the two points from step 2 and step 3 together, make a midpoint to confirm the exact location of the metal;
• Tips for ensuring the materials with magnetic or not: Magnetic / Non-magnetic metal indicator nearby the " 工" will appear
