Multi Depth Wall Scanner LCD Audio Alarm

This handheld wall scanner delivers reliable detection of wood studs, metal objects, and live AC wires embedded in walls, floors, and ceilings. Its LCD screen displays real-time scanning status and depth mode selection, while an integrated audio alarm provides instant auditory confirmation. Detection capabilities span five calibrated modes: 13mm, 25mm, and 38mm for wood stud identification; 38mm for ferrous and non-ferrous metal; and 51mm for live AC wiring. An intelligent microprocessor processes sensor input to accurately locate both edges and centers of targets. Power is supplied by a single 9V battery (model 6F22, not included), making it portable and ready for immediate deployment. Designed for clarity and consistency, it supports both novice home improvers and experienced contractors seeking dependable, repeatable results without calibration complexity.
