StudSensor i65 OneStep Electronic Stud Finder & Wall Scanner by Zircon

CenterVision® technology finds the center of studs in just OneStep™

StudSensor i65 finds wood and metal studs and joists up to 1-1/2 inches deep beneath the surface of walls, ceilings, and floors, in one simple step.

The easy-to-read LCD display indicates direction, edge, and center of stud, and the signal strength indicator helps distinguish between shallow and deep targets.

AC WireWarning® continuously detects hot AC wiring up to 3 inches deep for safety.

When the StudSensor i65 finds the center of the stud, it beeps and the SpotLite® Pointing System shines a beam of light over the center.
