Review: Fastest, most repeatable and most accurate stud (and power) finder that I've ever used! - 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.
Review: Does it's job perfectly - 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.

## Questions & Answers

**Q: will this sensor detect studs behind ceramic tile like one finds in a shower?**
A: Hello and thank you for your question. Unfortunately, there are really no sensors on the market that will go through both tile and the cement board used behind the tile for installation. I do have a couple of recommendations for you though. If the tile in your shower does not go all the way to the ceiling, you can find the studs on the wall above the tile and follow a straight line down to the location of where you would like to complete your project. My other suggestion would be that if the tiled wall where you would like to find the stud is an interior wall, you can find the stud on the other side of the wall (maybe its in the hallway), and measure the distance to a fixed point. Then you can extrapolate the same distance to the tiled wall to locate your stud.

**Q: Can you use this on a textured ceiling or does the surface have to be smooth?**
A: Good question and thank you for reaching out. The simple answer is yes, you can use the M150 on a textured surface. There are a couple of issues to be aware of however. The unit will work best on a smooth surface but will work on texture. Depending on how much texture is on the ceiling can effect the results. It can possibly give off false readings if the texture is heavy. While using the unit on the ceiling, if you think you have located a stud/joist, continue to hold down the button and run the unit along the length of the stud/joist. Studs/joists typically will run the entire length of the wall/ceiling. This way you can verify your findings.

**Q: Is it sensitive to insulation in the wall?**
A: Great question. Our sensors use the change in density to find hidden object behind the drywall. Our engineers have adjusted the amount of sensitivity that the sensors can detect so that insulation will not be detected because it does not have a high density.
Short answer: No, it will not detect insulation.

**Q: Will find aluminum studs used in RV's?**
A: Yes it will find aluminum studs behind drywall.

### ⭐⭐⭐⭐⭐ Amazing!
*by W***R on December 14, 2025*

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!
