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,
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.
