## Description

The Zircon StudSensor A100 Wall Scanner and Stud Finder helps you locate the edges of wood and metal studs behind walls quickly and accurately. Featuring WireWarning Detection, it alerts you to the presence of live, unshielded AC wires to help prevent accidental drilling or cutting. The easy-to-read display and ergonomic design make it simple and comfortable to use, whether you're hanging shelves, mounting a TV, or completing other home improvement projects. Built for reliability and precision, the A100 delivers dependable results for both DIYers and professionals.

Review: Works good - Good stud finder for the money. It's easy to use and does a good job at locating studs in the wall. The size is not bad as it fits comfortably in my hand with no problems. The accuracy for the most part is good but like almost every one of these I've used, it'll always have its moments where it doesn't seem to do right. But it ends up working out fine and gets the job done.
Review: Mounted a TV with it with no guessing - I hate stud sensors and stopped trusting them but you can’t spend all the time in the world trying to find screw heads with a magnet or trusting builders to put studs at 16” on center. I’ve hung a big TV and a climbing hangboard with this and it’s proven itself as being accurate and reliable. I would recommend. It does a good job of displaying the spot to mark for the center of the wood not like the older styles that only beep at the edges.

## Features

- ACCURATE STUD DETECTION – Detect with Confidence: Reliably finds the edges of wood and metal studs up to ¾ inch deep for secure mounting of TVs, shelves, and cabinets. The precise scanning helps minimize surface damage and ensures every installation is solid and level.
- ADVANCED WIREWARNING TECHNOLOGY – Smart Safety Scanning: Instantly alerts you to live, unshielded AC wires up to 2 inches deep to avoid drilling into electrical lines. This smart safety feature makes the tool essential for any project involving walls that may conceal electrical lines. A must-have wall scanner and wire detector for safe, accurate work.
- EASY-TO-READ DISPLAY & AUDIO INDICATORS – Know Before You Drill: Alerts you instantly to live, unshielded AC wires up to 2 inches deep to prevent accidental drilling into electrical lines. Whether you’re working in a brightly lit room or a dimly lit space, the display ensures quick, confident readings every time.
- ERGONOMIC & DURABLE DESIGN – Built for Comfort and Control: Designed with user comfort in mind, the contoured grip fits naturally in your hand to provide steady control and reduce hand fatigue during extended use. Its compact, lightweight body allows for smooth scanning across walls, ceilings, and even textured or uneven surfaces.
- PERFECT FOR DIY AND PROFESSIONAL APPLICATIONS: Ideal for hanging artwork, TVs, shelves, cabinets, or mirrors, this stud finder delivers reliable results for both casual home projects and professional construction jobs. Requires one 9V battery (not included) to deliver powerful, consistent energy for precise, reliable scanning and long-lasting operation.
- IMPORTANT: WireWarning Detection is a safety alert, not a wire locator. It warns of live, unshielded AC wiring nearby but does not identify exact wire position. For precise wire locating, choose a model with AC Scan Mode.

## Questions & Answers

**Q: I need the scanner dimensions so I can get a case?  I need the scanner dimensions, not the package dimensions.**
A: 7.5” X 3.5” X 2”

**Q: Do any of you that have the A250c have any recommendations for a hard or soft case? Perhaps one with a durable zipper?**
A: What you might try is small pistol case that is foamed lined, it also would allow ec=xtra space for misc tools,

**Q: Can it find stud deep behind fiberglass shower?**
A: Probably.  I just tried mine on my fiberglass shower and it did no problem.  It has deep scan.  2 things:  1, most fiberglass showers don't go all the way to the ceiling, so you can probably get a certain mark of the stud above the shower surround.  2. if your shower goes all the way to the ceiling, then this should work-- but some fiberglass surrounds have a huge gap of air behind them.  You might run into accuracy problems if it juts far from the wall to accommodate a big shampoo alcove or handles built in.  

I think this is the stud finder to try, though, since I just got  it to work with mine which has at least an inch of air gap between the fiberglass and where the wall would be.

**Q: Will this detect metal furring strips behind 5/8 inch sheet rock?... Without picking up rebar embedded in the concrete behind the furring strips?**
A: The MT6 will locate rebar in 6 inches of concrete  the M200 locates metal behind sheet rock up to 1 inch

### ⭐⭐⭐⭐ Make sure you use new batteries
*by D***K on November 30, 2024*

I thought this product would be easy to use, but I continually kept getting error messages and beeping. It does not seem very reliable or accurate Update: After reading online, it seems that the malfunctioning may have been caused by the fact that the battery I was using was a few years old (although unused). I replaced with a newly purchased battery, and it seems to be working fine now. I like that the light arrow shows you where the edge of the stud is
