Ferrous metals: 110 mm Nonferrous metal: 110 mm Live wire: 50 mm Wood (nonmetal): 25 mm Key benefits Helps prevent damage during drilling or mounting by locating metal, live wires, and wood behind surfaces. Detects ferrous metals up to 110 mm and nonferrous metals up to 110 mm for reliable material awareness. Detects live electrical wires up to 50 mm to improve safety when working near electrical systems. Identifies wood (nonmetal) up to 25 mm to guide fastening and anchoring decisions. Clear, straightforward detection limits support quick planning and accurate placements. Compatibility and usage Designed for use in environments where metal, live wires, and wood may be present behind walls, ceilings, or panels. Suitable for common interior construction scenarios such as home improvement, mounting, and DIY renovations. Provides consistent detection within the listed depths to help you choose safe drilling and anchoring points. Use scenarios Planning a wall mount for a TV or shelf: locate ferrous and nonferrous metals behind the surface and check for live wires before drilling. Electrical retrofit or outlet installation: identify live wires up to 50 mm to avoid failed wiring or accidental contact. Cabinet or fixture installation in or renovated spaces: detect hidden wood elements up to 25 mm to find suitable fastening points without damaging concealed components.
