Product Description

Higher Accuracy. Better Technology

The Franklin Sensors Family

Shows 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

The ProSensor M210 has 13 accuracy-enhancing sensors. In comparison, other stud finders have only 1-2 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?

For best results, use two brand new AA 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.

Customers say

Customers find the stud finder accurate and easy to use, with no calibration needed, and appreciate its ability to find every stud every time. The device works well on double thick drywall and identifies electrical wires behind drywall, with one customer noting it accurately shows the outline of studs. While customers find the build quality solid, opinions on value for money are mixed, with some considering it worth the price while others find it overpriced.
