This is a high-quality digital wall detector, a metal beam center detector with the function of detecting metal and wires. Multifunctional wall detector, metal detection, wood detection, wire detection, accurate detection, wide range of applications. The wall detector can detect metal, wood beams and live cables in walls, ceilings and floors (referring to walls, ceilings and floors of conventional concrete, tiles, wood boards, etc.). Features: Multifunctional wall detector, metal detection, wood detection, wire detection, accurate detection, wide range of applications. LCD screen design, accurate positioning, intuitive display, simple operation Five-in-one detection mode, can detect wooden poles, metal positions and live wires in the center of walls made of wood boards and gypsum boards, and has AC alarm function. There are two gears for detecting wood, 0.79 inches (20mm) and 1.5 inches (38mm), which can be adjusted as needed. It can be used to detect metal pipes with a wall thickness of less than 3.94 inches (100mm). It can also be used to detect live wires in walls with a wall thickness of less than 1.97 inches (50mm). Applicable scenarios, the wall detector can detect metal, wooden beams, live wires in walls, ceilings, and floors (in conventional buildings, it refers to walls, ceilings, floors, concrete, tiles, wooden boards, etc.).
