Franklin Sensors ProSensor M210 Stud Finder with 13-Sensors, Wood & Metal Stud Detector/Wall Scanner, Live Wire Detection

Finding a reliable stud finder has always been a challenge—until I got my hands on the Franklin Sensors ProSensor M210. This isn’t just another hit-or-miss wall scanner; it’s a game-changer for DIYers and professionals alike.Unboxing & First ImpressionsRight out of the box, the ProSensor M210 feels solid and well-built. Unlike flimsy, outdated stud finders that rely on single-point scanning, this one boasts 13 precision sensors, which means no more second-guessing. It’s designed for accuracy, and you can tell immediately that this tool means business.Performance That Stands OutI tested this on multiple surfaces—drywall, plaster, and even textured walls—and the M210 delivered flawlessly every time. Instead of scanning multiple times to confirm a stud’s location, this device displays the entire width of the stud at once, saving time and eliminating uncertainty. The bright LED indicators are easy to read, making stud location a breeze.The live wire detection is another standout feature. It provides an added layer of safety when working near electrical wiring—something most budget stud finders fail at.Why This Stud Finder Beats the CompetitionHaving used other stud finders, I can confidently say that the M210 blows them out of the water. Compared to models that require slow swiping and recalibrations, this one provides instant and precise readings. No need to hold down a button or guess where the stud actually starts. No calibration needed – just place it on the wall and scan! Durable and well-built.Final Verdict – Worth Every Penny!If you’re tired of false positives, misreads, and endless rescanning, the Franklin Sensors ProSensor M210 is the ultimate solution. Whether you’re a DIY enthusiast, contractor, or handyman, this stud finder will make your work easier, faster, and more accurate.

Ordered this to replace a Walabot+ and an old stud finder. This unit really works just as advertised and gives a good indication of where the center of the stud is. Really easy to use, especially compared to older units and the Walabot+, which requires a USB connection to your cell phone. Highly recommended.

I looked at a lot of stud finders on YouTube and from Amazon reviews. I decided that the Franklin stud finder was the best for the money. I am very pleased with it. It accurately detects wood and metal studs and also locates live electric wires. It's easy to use. The multi-light sensor indications lets you visually see the width of the stud and a green light indicates the center of the stud. This is much easier the quicker that other stud finders where you need to locate the edge of the stud and then determine the center. Runs on two AA batteries which are easy to find, easy to replace and cheap to buy. Changing batteries is a very easy process and does not require having to remove a screw.

I own an older model of Franklin Sensors' stud finder, and I bought this newer model to increase the precision of my stud detection. The newer model has more LEDs with reduced spacing between LEDs, which makes it easier to identify the exact center of your studs. The new model appears to be very accurate and precise. I also appreciate the small bubble-level, which helps you keep the tool horizontal during usage, further improving the accuracy.I'm just giving it 4 stars not 5 for 2 reasons:1) The older+cheaper stud finder from Franklin Sensors seems to function fine with NiMH rechargeable AA batteries that are charged > 1.3 volts. This means that if your AA batteries are charged half-way, the older model will work fine. The newer model doesn't light up unless the AA batteries are >= 1.4 volts (maybe 1.35... maybe 1.38... I don't know exactly). The NOMINAL voltage of NiMH rechargeable AA batteries is 1.2 volts. In practice, high-quality AA NiMH rechargeable batteries (Sanyo Eneloop, Amazon Basics, etc) can reach a voltage slightly above 1.4 volts when they're fully charged. At 90% charge, the voltage generally drops somewhere between 1.3 and 1.4. I've used this stud finder with freshly-charged high-quality NiMH AA batteries, and it works great. On one project, I then tried to use it again the next day with those batteries after maybe just 20 minutes of usage the prior day, and it wouldn't turn on. After I recharged my batteries to 100%, it continued to work.Alkaline AA batteries have a nominal voltage of 1.5V. I don't like to use disposable batteries because I find them to be wasteful. I have lots of devices that will function fine with rechargeable batteries that have a voltage > 1.2V or 1.3V. It's unfortunate that this stud finder can only work with batteries charged > 90%. For me, it just means that I have to fully charge a pair of batteries before I use the tool. Since I know this, it's OK, but it's inconvenient. I think I would still use the new one that requires fully-recharged batteries (>90%) over the older one that will work fine with moderately-charged batteries (>50%) since the new one is more precise and has the convenient integrated level. Still, Franklin Sensors could have added a voltage regulator circuit to this tool that would have allowed it to operate totally fine with batteries >1.3V, which would have made it much more convenient to use. If you're a professional remodeler who needs to find a lot of studs over the course of an entire day, you probably need to bring a spare pair of AA rechargeable batteries plus a charger to your job site and possibly recharge and swap the batteries at least once per day to use this tool.2) They really could have done a better job designing the cover for the battery compartment. It's actually better on this model than the older model, but neither are great. It's cumbersome to open the battery compartment, and, over time, the cover can get loose while you're using the tool. They could have designed the cover with a simple hinge and thumbscrew or some other locking mechanism that would be less prone to loosening over time.It's still a great tool. Despite the shortcomings, it's still the best stud finder that I've ever used. I mounted some slat walls and shelf brackets in a storage closet in my house, and I was able to easily find the center point of the studs behind my drywall with this stud finder.

The media could not be loaded. This is by far the most accurate and reliable stud finder I’ve used. The sensor is impressively precise, making it easy to locate studs without second-guessing. It’s lightweight, well-built, and the display is clear and easy to read. Simple to operate right out of the box. If you’re tired of hit-or-miss results, this is the upgrade you’ve been looking for.
