Product description
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

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).
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.
