Zircon M3 71851 Stud Sensor, 3/4″ (19 mm) Depth Scans

The Zircon SuperScan® M3 Stud Sensor offers reliable wall scanning performance with advanced Target Control® (TC™) Level 1 Technology, designed to help pros and homeowners locate wood studs while reducing false positives from hidden metal elements like pipes, brackets, and ductwork. Whether you’re mounting shelves, installing cabinetry, or running conduit, this scanner identifies the center, edges, and direction of wood studs up to ¾” (19 mm) deep, providing consistent, real-world accuracy. With four distinct scanning modes—TC, StudScan, DeepScan®, and Metal Scan—you’ll get the detail and confidence you need to tackle tough jobs across drywall, paneling, and other surfaces.

From its ColorTrip® backlit display to the SpotLite® Pointer and Target Spotlight, the M3 combines multiple visual indicators to pinpoint studs and metal targets with precision. Electricians, carpenters, HVAC installers, and general contractors will appreciate the added safety provided by WireWarning® Detection, and the convenience of ACT™ Auto-Correcting Technology, which automatically adjusts for common errors such as starting a scan over a stud.
