Zircon StudSensor A100
Edge Finding Stud Finder with WireWarning Detection
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.
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.
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.
The Key to Success is the Battery
The installation of a fresh battery with an extended expiration date is required to steadily power the integrated screen in Zircon tool.

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.

There was a problem filtering reviews right now. Please try again later.
This is my favorite sensor but bear in mind: they require the right 'touch' so you have to practice using them. I've read reviews which seem like the user wasn't using them properly: Put them against the wall, hit the button and sweep them left to right - the light should indicate the location of the edge of the stud. When you find a stud coming from one direction, move 8-12 inches to the other side and come at it from that direction and you should find both edges of the stud. Then before cutting or drilling DO IT AGAIN AND CONFIRM THE LOCATIONS. If you cannot reproduce the initial result keep trying until you do. With rare exceptions you will be able to find studs (some exception may occur in older houses with thick plaster and lathe that may conceal studs or in flipped houses with drywall over drywall that may conceal studs).
NOTE: that patience and repeating your measurements are important for all home improvement projects - but especially so for stud finding.
After running the stud sensor across the wall for a second time, it began locating studs every 6 inches or so. I decided to try one more time, and it didn't locate any studs in the wall at all.
I'm not sure if the product I received was defective or what, but now there are 3 useless holes in the wall of my apartment. AND I couldn't mount my son's furniture the night we moved into our apartment.
I ended up purchasing a basic magnetic stud sensor that worked without a problem.
I can happily say the Zircon e50 found each stud. The ability to know when you are on the edge of the stud vs. the center really does help you when mounting something 20lbs or more (especially by yourself). If you do something like a consumer in 2000-2005 when flat screens were just hitting the market, they tried to hang the TV on a single nail, like you would a picture. Of course it fell straight to the ground and almost hurt two people. A lot of understanding weight/motion in physics is intuition based on the strength you assume vs. the weight of the load (generally, even applies to circuits).
I have had the e50 stud finder act up a few times, but this was always fixed just by turning off and on or even just switch a setting. What happens is the stud finder visual/audio alert would start to go off too frequently and/or for too long of a time (knowing the width of the stud behind the wall). I believe this may have been happening when by chance I placed the stud finder on the wall for the first time directly onto a stud and then began to sweep the wall. If you did by chance lay the stud finder against the wall at a stud when you began to sweep along the wall, will it now report where the gaps are as the stud? If so, that would explain what is happening, but I thought this sort of problem would have been realized in R&D.
Much better than my other stud finders and the visual display is a life saver. Don't trust blind audio alerts when hanging a $2k-$3k TV, invest in or borrow a decent stud finder such as this e50. Also wanted to note that the e50 successfully does warn you of any voltage detected behind the wall, this is an excellent safety feature. Although these days, homes are built so the outlet does not run through or on the studs.
Question from Me:
What is the point of deep scan? Is that only for stone and other denser objects such as brick?
