Higher Accuracy. Better Technology
The Franklin Sensors Family
Shows the FULL WIDTH of studs
LEDs track stud center and edges simultaneously, showing single studs, double studs and irregular configurations other stud finders cannot detect.
More Sensors = More Accuracy
Conventional stud finders have 1 or 2 sensors. Franklin Sensors stud finders have up to 13 accuracy-enhancing sensors.
Deep Scan Always On
One mode finds it all! Franklin Sensors stud finders auto-adjust for different wall's texture, depth and material. Works through interior sheetrock/drywall and more.
Accurate and Easy
Just press and hold the button to start finding studs. No calibration required. Unlike conventional stud finders that give false readings, Franklin Sensors stud finders let you start scanning anywhere, even over a stud.

Frequently Asked Questions
What does the center green light mean?
In certain models, the center LED will turn green to indicate the exact center of the stud.
What does the single blinking light mean?
Several of our models now have a low battery indicator. When the battery voltage is low, the second LED from the right will flash. Replace with two brand new batteries.
Why do the LED lights flash when I first press the button?
In certain models, the LED lights will flash when you first press the button to assure you that the unit is on and receiving power.
What batteries can I use?
Not all of our models are compatible with rechargeable batteries. For best results, use two brand new, non-rechargeable, AA or AAA batteries (check instructions for details).

It worked, but not as well as I expected. I had to run it across a stud 3-4 times to get a good reading. In all, I will keep using it, but I will be sure to go very slowly and double-check the location of studs each time I use it.

I bought the Franklin Sensors ProSensor M50 from Amazon. A friend recommended this brand and proclaimed it the best for the price. I opened the battery compartment door of a brand new product just out of the package and - SNAP! The thin, flimsy piece of plastic designed to hold the door shut broke off. The battery compartment will not stay shut now.I did test out the sensor to see how it worked, in case I wanted to get a replacement. The sensor does not work properly. It has 5 lights on it to identify where the stud is located. The sensor would not light up any lights going across a stud from left to right, but would light up if being moved from right to left on the wall over the same stud. I also noticed that I would have the first 3 lights on (far outside, next, and middle) showing a stud. Then, after moving the sensor maybe 1/4" suddenly only 1 light was on. I don't know how a 1.5" wide stud could almost vanish in 1/4" of movement like that. The lights were dancing around a lot like this. It was bizarre and unusable. I had areas in my house where items were secured to studs with the help of a friend and his stud finder previously, so I know where the stud is located. This sensor was a bad guess and not an accurate measurement. Zero confidence this Franklin Sensors product knows what a stud is.I called a phone number for Franklin Sensors on a card inside of the package with the sensor. No one answered and no one returned the call after a few days before writing this review. I tried to give the company a chance and see how the customer service would be. But, no one even attempted to defend the garbage product I had bought. Sending this back to Amazon, and probably looking at another brand (or at a minimum another model without these flaws).

I couldn’t find a stud using my more expensive Stanley stud finder, found this read the reviews and bought one. Used it the first time yesterday and it was easy to use, accurate and fit well in my hands.

Used it after I got it to hang a tv and it was awesome. Next time I got it out to use it the button is jammed up. Don't know of anything that happened to it. Not sure if it was the way it was sitting in the pocket of my tool bag or what, but for the price it doesn't seem very sturdy.

I've used other stud finders but the ProSensor M50 feels good in your hand ergonomically and is super easy to use. It'll definitely do more than hang pictures. I've already used it in a construction setting and it performed very well. I feel like I can throw it in my tool box without worrying about it getting damaged. I'd buy it again except I don't think I'll need to.
