The Zircon i65 Stud Sensor locates the edges and center of wood and metal studs behind drywall. In standard mode, it detects studs up to 3/4" deep, while Deep Mode doubles scanning depth to 1-1/2" for thicker walls. The built-in WireWarning detection alerts you to live, unshielded AC wiring to help avoid dangerous contact while drilling or nailing.
