No frills, no fuss, no headaches, just works. Shows the left and right edges of a stud and of course, the exact middle of it. Shows where electrical lines may be, so you don't accidentally shock yourself. If there's any updates, I will post it. 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. ## Features - ACCURATE: More sensors = More accuracy. Conventional electronic stud finders have 1 or 2 sensors. The ProSensor M150 has 9, making it the best stud finder on the market - EASY: No calibration is required. Simply press and hold the button to begin scanning. Unlike other wall stud finders that give false readings, the ProSensor M150 lets you start scanning anywhere, even over a stud - SHOWS FULL WIDTH OF STUDS: Unlike magnetic stud finders that only find screws, the ProSensor M150 detects the full width of studs. The LED display shows the whole stud and double studs, and the middle LED will turn green to indicate stud centers - DEEP SCAN ALWAYS ON: One mode finds it all! The ProSensor M150 stud finder for drywall has deep detection of up to 1.5 in and finds both wood and metal studs - EXTRA FEATURES: The ProSensor M150 includes live wire detection for worry-free drilling. Two AAA batteries required, not included. NOT compatible with rechargeable batteries ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0917TH83L | | Brand | Franklin Sensors | | Brand Name | Franklin Sensors | | Customer Reviews | 4.4 out of 5 stars 4,268 Reviews | | Included Components | Range | | Item Dimensions | 5.51 x 2.99 x 2.01 inches | | Item Weight | 5.12 ounces | | Item dimensions L x W x H | 5.51 x 2.99 x 2.01 inches | | Manufacturer | Franklin Sensors | | Material | Plastic | | Material Type | Plastic | | Model | ProSensor M155 | | Number of Items | 1 | | Output Type | Digital | | Part Number | FSM15002HD | | Sensing Distance | 1.5 inches | | Specific Uses For Product | construction, home improvement, DIY projects | | Style | Compact | | Style Name | Compact | | UPC | 853435004415 | | Unit Count | 1 Count | ## Product Details - **Brand:** Franklin Sensors - **Item Weight:** 5.12 ounces - **Item dimensions L x W x H:** 5.51 x 2.99 x 2.01 inches - **Material:** Plastic - **Style:** Compact ## Images ![Franklin Sensors ProSensor M150/X990 9-Sensor Stud Finder, AC Wire Warning | Accurate Stud Finder Wall Scanner With Electric Wire Finder, Wood and Metal Stud Detector, Made in the USA - Image 1](https://m.media-amazon.com/images/I/71jScNanGFL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far it works exactly as needed *by P***R on July 17, 2026* It's only been a day since I've had it, but it's exactly what I needed. No frills, no fuss, no headaches, just works. Shows the left and right edges of a stud and of course, the exact middle of it.

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.

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. ## Frequently Bought Together - Franklin Sensors ProSensor M150/X990 Stud Finder with Live Wire Detection and 9-Sensors, Wood & Metal Stud Detector/Wall Scanner, Made in The USA - Case Compatible with Franklin Sensors ProSensor M210 710PRO 710 Professional Stud Finder.
