desertcart.com : 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 : Tools & Home Improvement

Review: Much better than single sensor stud finder - makes finding the stud fast, easy and accurate. Also the live wire detection has been really helpful in tracing wires behind the wall. This is a huge leap forward compared to my old single sensor stud finder!
Review: Unbelievably Impressive - Stud finder’s are a tool every person should have in their toolbox, whether you are a tradesman, handyman, or DYI. As for myself, I am handyman and invested in about 3-4 of them. The reason I decided to try this brand is the previous brands would detect a stud but it was hard to find out where the center was. This is very important because when installing or hanging something, you want to be in the center because the item you are installing can dislodge from the stud and cause damage to the home. In my opinion, THIS BRAND IS THE GREATEST and you will not purchase another after using this product. I speak so highly of this product because of its consistent accuracy of detecting the stud and reveals the center. You actually see the light bar detect the edge of the stud, and then as you maneuver the device, it tracks the stud until you notice a green light, which is the center of the stud-mind blowing!!!! I built a simulated wall with studs, electrical wiring, and sheetrock. So, I did not conceal all of the studs with sheetrock, therefore I could witness exactly what the device is monitoring. I placed the device on the sheetrock and maneuvered side to side, as if I am looking for a stud on a finished wall. As, I reached the edge of the stud, the light-bar illuminated red, which indicated the device had detected the stud. As I continued towards and over the stud, the light-bar continued to illuminate and tracked the stud. However, as I reached the center of the stud, there was a green light in the middle of the device. This product revealed the green light 10/10 tries and every attempt was directly in the center….did I hear someone say marksman! Another impressive feature of the product, “MX150/X990 with live wire detection,” there is an amber lighting bolt on both sides of the device, therefore it can detect live wires. To test this feature, I wired an outlet on two different studs and on opposite sides (left and right), So, not only did the green light reveal the center but also the side the electrical wire was secured. Shockingly, 10/10 times, the amber lighting bolt was correct every time I maneuvered the device close to the wire or over the stud. The product arrived in a small box and neatly seated inside a plastic wrapping with instructions and a thank you card. The instructions were easy to read, clear to understand, and imprinted on the bottom of the device. Once, you remove the item from the box, there is a black cover, and on the left side, there are about 3-5 lifted lines. You gently push away from you and don’t go too fast because on the oppose side of the removable cover are slide inserts, which can break if you are not careful. The product is very durable and thoughtfully constructed. So, nothing should break unless you handle the product very aggressively. As the instructions state, the product does not get shipped with batteries, so you will have to purchase or if you have some around the house, you will need (2xAAA) batteries. After inserting the batteries, reinsert the battery cover, and you are ready to go. Above the battery cover, the handle has 3 wavy indents which are purposely designed for your fingers, typically the index, middle, and ring ringers. Below the handle is a small arch with lifted lines, which is designed for seating your thumb. Now, you have a full grip on the device and it will not fall. After, you have a comfortable grip position on the handle, compress your three fingers and you should notice the device do a quick flash of the led bars. After, you will have to test the device. Do so by compressing the device with your three fingers and with the opposite hand, not holding the device, way you index finger under. You should notice the led bar tracking your finger. Your finger simulates a thin space then density, just like a finished wall with studs-Genius! Once the device is able to track your finger, now you can test the device on the walls and find those studs. Just an fyi, the product was thoughtfully designed to operate ambidextrously (both hands). I was able to hang pictures, televisions with brackets, electrical outlets, and basically anything you want to hang on a wall which you will fasten into the stud. Each attempt, the device pinpointed the of center of the stud and I did not have any self doubt. Overall, I am extremely impressed with this product and very happy with the purchase.

## Features

- 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

## 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.

### ⭐⭐⭐⭐⭐ The Worst Case Scenario (Maybe)
*by J***M on May 24, 2026*

Having had a basic Zircon unit from around 2005, it was at times frustrating to use with concerningly inconsistent results. You'd get a beep, then pick it up and try to place it over a stud bay, reset it and try again, and then there would be nothing where the prior hit was. Studs would seemingly move as if something changed in The Marix or the house was dynamically rearranging itself. Then I bought a magnetic stud finder (Hanson) which is great at finding drywall screws. That simple solution works most of the time, but not always: I have a home office that's a finished room in my barn. Inside the barn is an old carriage house that someone built a barn over without tearing it down. The history is pretty interesting to me. My office is in the old carriage house part, and to run new outlets, Ethernet, hang shelves, etc, I obviously needed to know where the studs are. The walls out there are an odd combination of weirdly spaced studs and there are old window openings that have since had studs placed in them and have been walled over. Some of the studs are 14" apart, some 18", a couple are standard 16" and there's a 20ish" stud bay in one spot. I'd love to know what the history is there. Maybe an inhebriated farmer with a hammer? In some places there's some kind of exterior cladding and siding in there with a gap between it and other material. Some of the drywall was hung from this intermediate material rather than the "studs," (using that term loosely) so using the screws as a guide with the magnet was useless. The interior wall looks completely normal, but finding studs in the mess beneath it was an absolute nightmare. In desperation, I bought this device. While unsurprisingly, even it struggles with the scenario above, I was able to map out the odd placement of studs in the wall, including the outlines of old windows. That was still a tedious process, but was infinitely easier with this device. I love that you can see the thickness of the studs, since some of the lumber in there is pre WW2 and is actually true to dimension. You can also find doubled up studs easily. The tech has come a long way over the years and in my opinion this is absolutely worth the money.
