Higher Accuracy. Better Technology
The Franklin Sensors Family
Shows FULL WIDTH of studs
See more than just a point on the wall. The LEDs track stud center and edges simultaneously, giving you a full visual of the stud.
More Sensors = More Accuracy
Conventional stud finders have 1 or 2 sensors. The ProSensor M70 has 7 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?
The ProSensor M70 is not compatible with rechargeable batteries. For best results, use two brand new, non-rechargeable AAA batteries,

I like the stud finder. It's simple and easy to use. If you're using it to locate a stud to hang something on the wall, then it is good for around the house. This is not a fancy, professional model, that detect wires and other objects. It's easy and simple to use for around the house

I use a stud finder all the time and when my old stud finder finally gave up, I bought the Franklin ProSencer M70 and I can't believe how easy it is to use, I just finished a master closet and M70 found the center of every stud I had to mount to. This is definitely a great tool to own.

I purchased the 7-sensor stud finder so I can find the studs in my walls for a few projects I hope to be working on around the house soon. I had some issues with it due to some bad batteries at first but after changing them out it's worked more or less how I would expect it to.You can run your finger across the back of it to make sure the product is working correctly.The only complaint I have about the product is sometimes it makes the stud out to be larger than it actually is but this has only happened twice so far. I've marked a few spots with tape and the indicator seems to be reading fairly accurate. I would probably opt for one with a few more sensors but over all it does what I need it to do.It uses two AAA (Triple A) batteries that are housed inside the black strip across the handle. When pressing the button it should flash the lights but if it doesn't and you aren't sure if it's working, like I said, just hold the button and slowly run your finger across the bottom of the device.

It makes sense to have multiple lights on any stud finder. I have some that are much wider but are too big and unnecessary. This small, 7 sensor is perfect. I have one in the shop, one in the house and gave them to my sons.

Fairly intuitive to use but not always reliable/trustworthy. My first time using it I was determined to screw smack dab in the middle of the stud so I moved the finder around until I had struck gold and got the green light. Little did I know that the stud finder also finds wires and I screwed right into the wire. Good little stud finder but could use a few more features so you know what you’re screwing with.

Love that it lets you “see “ both sides of the stud easily just by sliding the finder one direction

This actually works rather well, unlike most you can buy. You still need to figure out what the results mean but, when the centre red led turns green, you really are over the centre of the stud. Only detects studs, so a pipe/cable detector is still useful but these work ok on most others,

I previously owned the larger and more expensive Franklin stud finder (which had a built in level). I seemed to have misplaced it so I bought this smaller and much cheaper one as a replacement. I was very surprised at how much I liked it. It has a green light in the middle to highlight the center of the stud and red lights to highlight the edges. It's actually perfect! It does the same job as the large one (minus the leveling) at half the price. I haven't been this happy with a product purchase in a long time. I thought I downgraded but it doesn't feel like it.

This is superb, so easy to use. It has been put to good use in my property and has helped me to find multiple wooden batons in the walls for securing tv wall brackets. It also easily detects electrical cables.Please be aware that it does not come with batteries, AA are required.

it's more affordable and does the job like other models, it can accurately detect studs behind drywall.
