More Sensors = More Accuracy The ProSensor M210 has 13 accuracy-enhancing sensors. In comparison, other stud finders have only 1-2 sensors. Deep Scan Always On One mode finds it all! Franklin Sensors stud finders auto-adjust for different wall's texture, depth and material. Works through interior sheetrock/drywall and more. Accurate and Easy Just press and hold the button to start finding studs. No calibration required. Unlike conventional stud finders that give false readings, Franklin Sensors stud finders let you start scanning anywhere, even over a stud. Frequently Asked Questions What does the center green light mean? In certain models, the center LED will turn green to indicate the exact center of the stud. What does the single blinking light mean? Several of our models now have a low battery indicator. When the battery voltage is low, the second LED from the right will flash. Replace with two brand new batteries. Why do the LED lights flash when I first press the button? In certain models, the LED lights will flash when you first press the button to assure you that the unit is on and receiving power. What batteries can I use? For best results, use two brand new AA batteries (check instructions for details). What materials do your stud finders detect through? Sheetrock/Drywall Our stud finders work best through a single layer of sheetrock/drywall. Lath and Plaster While many customers have reported success using our stud finders through lath and plaster, detection is not guaranteed due to irregularities in plaster thickness. Incompatible Surfaces We do not recommend using our stud finders through stucco, exterior siding, double layers of sheetrock/drywall (common in condos, townhomes and home theaters), tile, wood flooring, carpet or roofing. Review: ⭐⭐⭐⭐⭐ Accurate, Fast, and Worth Every Penny - The Franklin Sensors ProSensor M210 is by far the best stud finder I've owned and I’ve owned a fair few. Unlike traditional stud finders that require constant calibration, this one is incredibly easy to use—just place it on the wall and it instantly shows the full width of the stud with its multiple LED sensors. It's accurate, reliable, and has saved me a lot of time hanging TVs which I do professionally. The wider detection area gives me much more confidence than models with less sensors. Once the stud is found, the red lights illuminate. After moving the finder left and right across the stud a green light illuminates to show the centre. Brilliant! The build quality feels solid, the grip is comfortable, and the display is easy to read. Even if you're not a DIY expert, this tool makes locating studs simple and stress-free. If you're looking for a dependable stud finder that just works, the Franklin Sensors ProSensor M210 is absolutely worth the investment. Highly recommended!

This allows a more precise indication of the stud limits. It also has 2 AC voltage indicators at each end in case live wires exist beneath the wall or ceiling surface you are scanning. These "upgrades" were worth the additional $5 to me. **Q: Will it work on a sprayed on rough ceiling?** A: Thank you for your question. Unfortunately our sensors do not do well with rough surfaces. Our stud finders function by sensing any change in density, and when the surface is very rough and bumpy it creates air gaps between the unit and the surface which leads to false readings. **Q: Puedo encontrar los stud de metal?** A: Yes, this can find metal studs. It works by finding any change in density behind the drywall, so it will find both wood and metal studs simultaneously. **Q: Does any model of the Franklin Sensors work better with sheetrock over old wood lath walls than the others??** A: Our best and most accurate sensor is the M210. This stud finder has a maximum detection depth of 1.7". Depending upon the total thickness of the sheetrock over old wood and lath, this finder may be your best bet. We cannot guarantee that it will work however without knowing the thickness and the makeup of the materials. Good luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ Accurate, Fast, and Worth Every Penny *by A***R on 2 July 2026* The Franklin Sensors ProSensor M210 is by far the best stud finder I've owned and I’ve owned a fair few.

I needed to put up quite a few hand rails and this made finding the studs easy and to my surprise it even worked through the bathroom tiles, well worth the investment! ### ⭐⭐⭐⭐ Convenient to use but not accurate enough *by S***M on 11 January 2026* The design concept if good for making mutiple lights to detect the width of the stud. It is also convenient to use for no need to calibrate. However, it does give confusing reading and signal which does not make me confident enough to drill holes if I need to drill into a wall with unknown interior structure. However, if you already know there is only wooden stud and one or two main wires in the wall and you are unsure about where are they, the product can help. But if you are worrying about there are multiple wires and pipes inside the wall, likely you need a more accurate one. ## Frequently Bought Together - Franklin Sensors ProSensor M210 Stud Finder with 13-Sensors, Wood & Metal Stud Detector/Wall Scanner, Live Wire Detection - Franklin Sensors Official Stud Finder Case for the ProSensor M210, 710, 710+, T13, T11, X2100, X1100 (Case Only) - Franklin Sensors Light Level/Digital, Electronic, 12-inch Magnetic Torpedo Level, Vertical and Horizontal Leveler Tool with 2 Bubble Vials --- ## 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.fi/products/338872443-prosensor-m210-stud-finder-with-live-wire-detection](https://www.desertcart.fi/products/338872443-prosensor-m210-stud-finder-with-live-wire-detection) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-08-04*
