ProSensor Sapphire 9000 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 mean more precision. Conventional electronic stud finders typically contain 1 or 2 sensors. This model features 9, making it one of the most precise stud finders available.
EASY: No calibration needed. Simply press and hold the button to start scanning. Unlike other wall stud finders that often produce false readings, this device allows you to begin scanning anywhere, even directly over a stud.
SHOWS FULL WIDTH OF STUDS: Unlike magnetic stud finders that only locate screws, this unit detects the entire width of studs. The LED display reveals the full stud and double studs, and the center LED turns green to mark stud centers.
DEEP SCAN ALWAYS ON: One mode covers everything! This drywall stud finder offers deep detection up to 1.5 inches and identifies both wood and metal studs.
EXTRA FEATURES: This compact, accurate, and durable stud sensor requires two AAA batteries (not included). It is not compatible with rechargeable batteries
