Being a DIYer, this appeared to be a bit spendy for an item that one may use only occasionally.
But it is well worth the cost.
Solid, quality build.
Each stud was easy to find and existing wiring was also easily detectible.
And this was done through old plaster walls.
It was actually fun to use.
The instruction manual was well written.

5.0 out of 5 stars Franklin Sensors ProSensor M210 Stud Finder: A Game-Changer with One Caveat
Reviewed in the United States on May 5, 2024
The Franklin Sensors ProSensor M210 Stud Finder has earned its reputation as the world's best stud finder, and it's not hard to see why. With its advanced technology and intuitive design, locating studs behind walls has never been easier or more accurate. However, there is one small caveat to consider.

Let's start with the positives. The ProSensor M210 utilizes multi-sense technology to detect studs in real-time, providing instant feedback on stud locations with unmatched accuracy. Its wide scanning area and deep sensing capabilities ensure that no stud is missed, even in the most challenging wall configurations.

The ergonomic design fits comfortably in the hand, making it easy to maneuver and use, while the LED display provides clear visual indicators of stud locations for quick and precise identification. Whether you're a professional contractor or a DIY enthusiast, this stud finder streamlines the process of hanging shelves, mounting TVs, or any other task that requires locating studs.

However, it's worth noting that while the ProSensor M210 excels at detecting wooden studs, its performance with high voltage wires may not be as reliable. While it's generally accurate in avoiding live electrical wires, there have been occasional instances where users have reported inconsistencies in detection. As such, it's wise to exercise caution and verify electrical wiring with additional tools when necessary.

In conclusion, the Franklin Sensors ProSensor M210 Stud Finder sets the bar high for stud detection technology, offering unparalleled accuracy and ease of use. While its performance with high voltage wires may not be perfect, its overall reliability and effectiveness make it a must-have tool for any toolkit. Five stars for its game-changing capabilities and exceptional design.

This is my favorite. It is so easy to use and read. It is easy to get a hard case to protect the device and keep batteries handy so they dont leak inside the unit.
I love the design and now this model has the live wire readout, albeit a little obstructed behind your fingers but still functional. The live wire seems easier than other models I own so this remains my go-to.

4.0 out of 5 stars Accurate and Precise. Only works with alkaline or fully-charged rechargeable batteries.
Reviewed in the United States on January 18, 2023
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.

5.0 out of 5 stars Never using any other stud finder after this
Reviewed in the United States on September 6, 2024
If you have textured ceilings like I do and need to drill some holes into the beams, then you probably know how difficult it is to find the beams using a stud finder. The textures give a bumpy surface to move your typical stud finder along and you get inconsistent readings and false positives.

This 13 sensor stud finder is a bit more expensive than your typical stud finder but worth it in my opinion. I was able to easily see the width of the beam and quickly find the center accurately and quickly. There is no fancy LCD display, no settings to change. There's just one button and a row of LEDs but even with such a rudimentary experience, the information I get is more valuable than what I have been able to get on your typical stud finder.

After using typical stud finders for years and never being 100% confident in the reading, this is a game changer. So simple to use and gives you confidence you are drilling in the right spot. Well thought out with a built in level and pencil for marking your spot. A must have.

Works a heck of a lot better than my old one. It shows you the leading and trailing edge of the obstructions in the wall with a reliable, repeatable, precision.

This one is better than the Stanley I replaced it with. It actually will find a stud instead of just randomly beep. As far as the voltage sensor goes it’s kind hit or miss I only used it once tho so it could just be me.
