This wall detector provides fast, accurate detection of hidden objects behind walls, helping you avoid drilling into pipes, wires, or rebar and improving job efficiency for installation and renovation tasks. It is suitable for use indoors and outdoors. Key benefits Reduce risk during drilling and cutting by reliably locating metals, live wires, wood, and water pipes before work begins. Save time with clear positioning and graduated center dots that mark the exact location of hidden objects. Adapt to different job conditions using three detection modes to increase detection accuracy and speed. Main features and specifications Detection depths: Ferrous metal: 110 mm Nonferrous metal: 110 mm Live wire (110V/230V): 50 mm Wood (nonmetal): 25 mm Water pipe: 35 mm Three detection modes: metal detection mode/nonmetal detection mode, automatic detection mode, and live wire detection mode. Modes can be switched to suit different working conditions. Simple operation: short press the power button to turn on; long press for 3 seconds to turn off. Automatic power off after 3 minutes of no button activity. Graduated dots on the detector help locate the center of the hidden object for precise marking and drilling. Designed for reliable performance to locate ferrous and nonferrous metals, wood, and wires under common wall surfaces. Practical applications Mounting shelves, cabinets, and TVs: verify absence of hidden pipes, rebar, or live wiring before drilling. Renovation and plumbing work: locate water pipes and metal supports behind walls to prevent accidental damage. Electrical and installation work: detect live wires and concealed metal conduits to plan safe routing and fixings. How it helps in real work Choose the appropriate detection mode for the target material to improve detection accuracy. Use the graduated center dots to mark the exact spot before drilling or cutting. Rely on clear depth indicators to assess how far objects are located under the surface. This detector offers clear, practical detection performance and straightforward controls for safer, more efficient wall work.
