It features live wire detection up to 2 inches, an easy-to-read LCD screen with SpotLite pointer, and quick calibration for precise, safe, and efficient wall scanning before mounting shelves, TVs, or cabinets. ## Description The Zircon® StudSensor™ A100 stud finder wall scanner helps DIYers and pros locate the edges of wood and metal studs and joists before common wall projects. Use it for shelves, mirrors, cabinets, TVs, décor, repairs and other fastening projects where finding a solid reference point behind standard drywall matters. For best results, calibrate before each scan. Hold the scanner flat against the wall, then press and hold the Power Button. Do not move the scanner during calibration. In 1–2 seconds, a short beep confirms calibration is complete. After the beep, slide the tool slowly while keeping steady contact with the surface. Scan from both directions to confirm stud edges before drilling or fastening. StudSensor™ A100 includes two scanning modes. StudScan Mode locates stud edges up to 3/4 inch deep, while DeepScan® Mode doubles the scanning depth up to 1 1/2 inches. The tool can scan through many common sheet materials, including bare wood flooring in DeepScan® Mode, linoleum over wood, gypsum drywall over plywood sheathing, dry wallpaper and uniform textured ceilings when protected with a thin cardboard barrier. It is not designed for ceramic floor tile, carpeting and padding, metallic wallpaper, damp freshly painted walls, lath and plaster walls, foil covered insulation board, glass or other dense materials. Always verify readings before drilling. WireWarning® Detection alerts to live, unshielded AC wiring up to 2 inches deep while scanning in StudScan and DeepScan® Modes. This feature is a supplemental warning only and is not a precise wire locator or a replacement for turning off power and following proper drilling precautions. SpotLite® Pointer, LCD screen, audio tone and the illuminated V marker groove help identify and mark stud edges more clearly. The patented over-the-stud alert lets you know if scanning begins over a stud. Requires one fresh 9V battery, not included. ## Features - Accurate Edge Finding for DIY Projects: Zircon StudSensor A100 helps locate wood and metal stud edges, while the LCD screen, audio tone, SpotLite Pointer and V marker groove help guide marking before hanging shelves, mirrors, cabinets or TVs - Correct Calibration for Better Scans: Hold scanner flat against the wall, then press and hold the Power Button; in 1–2 seconds, a short beep confirms calibration is complete. Do not move during calibration, then slide slowly to scan - Two Scanning Modes: StudScan Mode finds stud edges up to 3/4 in. deep for standard scans, while DeepScan Mode reaches up to 1 1/2 in. to help locate studs behind thicker walls, ceilings and surfaces - Detects Live Electrical Wires: WireWarning Detection helps alert you to hot, unshielded electrical wires behind the wall, continuously detecting them up to 2 in. deep while you scan for studs or metal before drilling or mounting - Low Battery Indicator: Lets you know when battery power is too low for proper scanning, helping you replace it with a new 9V alkaline battery with an extended expiration date for optimum performance ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B09CV9TZWW | | Best Sellers Rank | #5,226 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #11 in Stud Finders & Scanners | | Customer Reviews | 4.4 4.4 out of 5 stars (878) 4.4 out of 5 stars | | Item Model Number | 72296 | | Item Weight | 8.4 ounces | | Manufacturer | Zircon | | Package Dimensions | 9.13 x 6.38 x 3.66 inches | ## Product Details - **Brand:** Zircon - **Color:** Yellow - **Batteries Required?:** Yes - **Material:** Plastic - **Power Source:** Battery Powered ## Images ![StudSensor™ A100 Stud Finder w/Live Wire Detection | Easy-to-use stud finder - Image 1](https://m.media-amazon.com/images/I/71rp32E5UTL.jpg) ## Available Options This product comes in different **Size** options. ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value for the price *by on Reviewed in the United States June 26, 2026* Love this little stud sensor! Works really well and very easy to use! ### ⭐⭐⭐⭐⭐ Zircon A100 Stud Finder *by on Reviewed in the United States July 4, 2026* It works! It works GREAT! I finally found a good stud finder…one that actually works! This is powered by a 9v battery instead of 2 AA batteries. Maybe that is why it works better than my other ones. But I am very happy with my purchase and I am posting a video so you can see it work for yourself. ### ⭐⭐⭐⭐⭐ Good Stuff! *by on Reviewed in the United States March 18, 2026* Had this same one for 15+ years and it quit working. Replacing with the same one. ## Frequently Bought Together - Zircon StudSensor A100 Wall Scanner and Center/Edge Locating Stud Finder with WireWarning Detection - Laser Level Line Tool, Multipurpose Laser Level Kit Standard Cross Line Laser leveler Beam Tool with Metric Rulers 8ft/2.5M for Picture Hanging cabinets Tile Walls by AikTryee. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/365611800-studsensor-a100-stud-finder-w-live-wire-detection-easy-to](https://www.desertcart.co.th/products/365611800-studsensor-a100-stud-finder-w-live-wire-detection-easy-to) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-15*
