ProSensor M90 9-Sensor Stud Finder Wall Scanner Accurate Wood and Metal Stud Detector, Made in the USA, Shows Full Width of Studs, No Calibration Required

ACCURATE: More sensors = More accuracy. Conventional electronic stud finders have 1 or 2 sensors. The ProSensor M90 has 9, making it the finest stud finder on the market.
EASY: No calibration is needed. Simply press and hold the button to begin scanning. Unlike other wall stud finders that give false readings, the ProSensor M90 lets you start scanning anywhere, even over a stud.
SHOWS FULL WIDTH OF STUDS: Unlike magnetic stud finders that only locate screws, the ProSensor M90 detects the full width of studs. The LED display shows the entire stud and double studs, and the middle LED will turn green to indicate stud centers.
DEEP SCAN ALWAYS ON: One mode finds it all! The ProSensor M90 stud finder for drywall has deep detection up to 1.5 in and detects both wood and metal studs.
EXTRA FEATURES: The ProSensor M90 stud sensor is compact, precise, and sturdy. Requires two AAA batteries, not included. Not compatible with rechargeable batteries
