Comprehensive Scanning Modes Five scanning modes address a range of materials and depths. Wood and metal scanning works from 1/2 inch to 1.5 inches, with metal detection up to 2.36 inches and livewire detection up to 2 inches. Enhanced Precision Technology An advanced chip delivers heightened accuracy and quick stabilization to pinpoint metal, wood, and AC wires behind walls and ceilings. This reduces guesswork, improves safety, and saves time during interior renovations. Requires one 9V battery for power, not included. Smart LCD Display and Audible Alerts The backlit LCD display remains visible in low light and shows the location and depth of detected objects. An audible beep signals proximity to an object, aiding precise mounting of shelves, frames, and electronics. Userfriendly Operation The onebutton interface powers the unit on and off and toggles between modes. The straightforward operation is suitable for both DIY enthusiasts and professional users.
