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 useful is it
Answer:	hi, my dad wrote a comment on this last time and he isnt here right now, but he talked to me about it and he ended up throwing it away- thats how bad it was. it didnt work for him at all. hope this helps.
Question:	Does this device work AFTER it has been properly calibrated as per youtube video
Answer:	Nope. I've tried everything. I've even exchanged it for a new one. I have an old Stanley 77-110 basic model stud finder which still works and finds studs that the fay max can't locate. I thought I'd upgrade and had my son buy me the Fat Max for my birthday, big mistake. Google it and see all the other disappointed owners, this tool should be recalled.

Product description

The StudSensor A100 is Zircon’s newest edge locating electronic stud finder that is sold exclusively on Amazon. The A100 is designed with a smooth, ergonomic rubber grip allowing for a comfortable yet secure hold for any size hand, at any angle. This stud finder uses the most recent technology in density detecting software and circuitry. The scanner has 2 scanning modes to locate the edges of wood and metal studs and joists behind walls, floors, and in ceilings up to 1.5 inches (38 mm) deep. In StudScan Mode, the SS A100 locates the edges of shallower wood or metal studs up to 0.75 of an inch (19 mm) deep. Switch over to DeepScan Mode to double the scanning depth to 1.5 inches (38 mm). This stud sensor is programmed with a Wire Warning Detection feature that indicates the presence of live unshielded electrical wires up to 2 inches (50 mm) deep when using either stud scanning modes. Finding studs using this edge finding tool is simple. To get started, install one brand new 9V alkaline battery (not included). Place the unit flat against the wall and press the Power Button to calibrate the sensor. Once you hear a beep indicating calibration is complete, continue to hold the Power Button and slowly slide the tool across the surface. The easy-to-read LCD 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. Make sure to note whether the Wire Warning Detection is alerting you to live, unshielded AC wiring before drilling between the two marks into the center of the stud. With the Zircon StudSensor A100, you can safely maneuver through the most complicated of projects with the professional confidence that comes from owning a Zircon.

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.

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?

User questions & answers

Question:	Can you use this stud finder on the ceiling
Answer:	I have not found a way for it to do that. When mine reaches the end of a countdown, it beeps and then starts counting up. It does not beep again unless I stop it, reset it, and start the countdown again. It sound like you are looking for a device that will signal you at a preset or user defined interval. I don't believe this device is capable of doing that.
Question:	Some people recommend buying multiples of these. What is the purpose of that
Answer:	I tested starting the stopwatch (count up) and I was able to change the mode and start a countdown while the stopwatch was still counting up. I could stop the countdown, reset it, and start a new countdown while the stopwatch (count up) continued.

Answer:	The clear display package it comes in is considered to be the “case”. The display package opens up like a book once you cut the black band keeping the two sides together. If you’re expecting a traditional nylon case, then you will be disappointed. I was disappointed when I found out there was no nylon case, but the provided packaging works just fine for me now. Thank you.
Question:	Can the device put out correct vertical lines if turned 90 degrees
