Best studfinder I've ever seen. I tried a couple of others but they weren't giving repeatable results and weren't very good at actually finding studs, which is a problem. The Franklin ProSensor X990 gives me repeatable results every time. Another feature I like is that the leds will begin to turn red in the direction of the stud you're about to go over, and then shows the center led as green when you're in the middle of the stud. Works every time and only takes a few seconds to find the stud. Plus it also has two leds shaped like lightning bolts that light up when there's a power cable in the wall that you're going over. Since I had bought a Teslong Inspect-5ft borescope and had to drill holes in the same wall for drywall anchors, I used the anchor holes to inspect behind the wall and confirmed that in two different walls that there were indeed electrical cables behind the wall. In one case it was easy to expect power due to the wall switch being in that area, but in another, there was no clear outside indication that were was a power cable behind the wall so I was surprised when the Franklin's power indicators first came on. This is now my go-to stud finder since its so quick and easy to use and always on target. Very accurate and very sensitive, but doesn't give false positives, and is even ergonomically designed so it feels comfortable while moving it across the drywall.

I have used this stud finder multiple times throughout the house for DIY projects, such as mounting a stair rail to the wall, wire shelf bracket holders, and foldable brackets. It has, without issue, helped me find studs and reliably mark the middle of the stud for screwing or nailing. The multiple LED marks help easily determine where a stud is and where the center of it is. It also helps with finding potential live wires, as the electrical sensor will light up if it potentially detects a wire running near it. The only issue might come down to user error if you are not accustomed to finding potential stud locations and rely solely on the device. One should make sure there isn’t a possibility of something else being behind the wall, as it will detect but not identify the item it is marking. -Simple to use -Lightweight and portable -Accurate stud finder -Good value for the price; if you can find it under $40, buy it.

I recently moved and had loads of things to hang on the walls- cabinets, shelves, etc., all of which required a good ‘hit’ on a stud. I invested in the Franklin stud finder to update my lifelong Amish “knocking on the wall” method. I am happy to report that it works great! It has been 100% accurate in finding stud centers, and warning me when electric is nearby. It is very intuitive to use and saved me time and wall damage. I am a 76 year old man and I wish that I had one of these sooner. Highly recommended!

The Franklin Stud Finder is accurate and easy to use, it quickly detects wood and metal studs, and the live wire detection feature adds an extra layer of safety. The multiple sensors give a clear, reliable reading across a wide area, saving time compared to basic stud finders. The only drawback is that it’s a bit bulkier and pricier than simpler models, but the performance makes up for it.

This stud finder works soo much better/accurate than the one I lost. The multiple lights, and one turning green for center makes it super simple to find the stud center. The live wire detection works well - I ran it over a stud that had wires running down it from the ceiling to a plug, and it picked them up and lit up the lightning bolts. I think there was a slightly cheaper option without the live wire detection, but I think it's worth the extra for it. Great tool.

This Stud Finder is outstanding!!! I have 3 other cheap ones that I've purchased over the years. I tried them all on a project I was doing on the house and they failed. I went out to the internet and looked for what others were using. I stumbled on a construction website that had a conversation going about what the pros use. Most came back with this finder that I had never heard of. Amazing results!!! I threw the other ones in the trash and learned from my mistake. If I would have purchased this one years ago, imaging the money and time I would have saved, not including the frustration.

I needed a good stud finder to help mount a TV, which I had never done before. This worked perfectly for the job, identifying the studs, and even showing the electrical wires. I had an old stud finder from way back, but it was nothing like this one. This shows the exact location of the stud so you can tell when you are properly centered. I'd highly recommend for ease of use and value for the money.

I needed to mount a tv above my fireplace and used a B&D stud finder that I had. Needless to say it couldnt find anything. I tried a magnet and did find one screw. I finally decided to try a different finder and based on other reviews decided on this one. After receiving the unit I installed the required two AAA batteries (not supplied). As soon as I moved it accross the wall it not only found the edge of the studs but also showed the center. Being also able to detect wires is a bonus. Simple to use and worth the money.
