ACCURATE: More sensors = More accuracy. Conventional stud finders have 1 or 2 sensors. The ProSensor M90 has 9, making it the most accurate stud sensing tool on the market. The ProSensor M90 has a max detection depth of 1.5". The LEDs track the location of studs while displaying the center and edges simultaneously.
EASY: One mode finds it all! The ProSensor M90 adjusts for a variety of depths, materials and textures. No calibration required. Press and hold the button to begin scanning. Unlike other stud sensors that give false readings, the ProSensor M90 allows you to start scanning anywhere, even over a stud.
DISPLAYS FULL STUDS: The ProSensor M90 displays the center and edges of studs simultaneously, showing single studs, double studs, and irregular configurations that other stud finders cannot detect. Works through drywall/sheetrock and more!
DURABLE: #1 Rated by consumers and professionals, the ProSensor M90 stud finder is both accurate and durable.
MORE INFO: Uses common AAA batteries. Is NOT compatible with rechargeable batteries.

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 M90 is not compatible with rechargeable batteries. For best results, use two non-rechargeable AAA batteries.

What materials do your stud finders detect through?

Sheetrock/Drywall

Our stud finders work best through a single layer of sheetrock/drywall.

Lath and Plaster

While many customers have reported success using our stud finders through lath and plaster, detection is not guaranteed due to irregularities in plaster thickness.

Incompatible Surfaces

We do not recommend using our stud finders through stucco, exterior siding, double layers of sheetrock/drywall (common in condos, townhomes and home theaters), tile, wood flooring, carpet or roofing.

Frustrating battery compartment
Reviewed in Canada on July 24, 2024
Verified Purchase
It does what it needs to, and located studs that other stud finders didn't, but whoever designed the battery compartment has never used the product. It's a frustrating and fumbly experience. I'm unsure why rechargeable batteries don't work in this unit (I tried anyway), and I feel like that's an oversight in 2024. Instead you must buy single-use batteries.

Reviewed in Canada on February 24, 2025

I ordered this item twice and both the times even after using new AAA batteries the item won't work. Both the times after putting batteries in second sensor from right will blink for few seconds and then no other sensor is working. The quick test for moving finger around sensors doesn't work nor does any sensors work when kept against the wall.

Reviewed in Australia on January 8, 2020

Have used this a few times now & it is great at identifying exact location of studs.
It got a little confused one time (all lights illuminating across the wall). However, when used on the opposite side of wall it worked perfectly - so maybe there was something setting it off. Overall very pleased & would recommend over cheaper less accurate items.

Very accurate and easy to use
Reviewed in the United Kingdom on April 15, 2025
Verified Purchase
The most accurate stud finder I have used and I have used many different types. The LEDs light up red to show the width of the stud and when the centre of the unit is in the centre of the stud, a green LED lights up in the middle.

There is no calibration against the wall required. Just hold the button and go.

I've found of the unit has trouble finding a stud or is giving a random pattern, it is 99% because there are random studs in the wall.
