Key benefits Quickly and safely locate hidden objects in interior walls: detects metal, wood and live electrical circuits so you can avoid drilling into pipes, studs or live wiring. Reduces risk and saves time during installation and renovation by giving clear visual indicators and acoustic warnings when targets are found. Useful for professionals and DIYers working on interior decoration, mounting, cutting or remodeling tasks where hidden materials pose a hazard. How it solves problems Prevents accidental damage to pipes, studs and electrical wiring by identifying their position before you cut or drill. Helps plan and execute accurate installations (shelves, cabinets, fixtures) by showing where supporting structures and wiring run inside walls. Minimizes costly repairs and downtime caused by hitting concealed components. How it works The instrument senses changes in material density beneath a surface; those changes produce fluctuations in the detector’s frequency. When metal, wood or live circuits are detected, the device provides visual indicators and acoustic warnings to pinpoint the location. Key functions and performance Detects: metal, wood and live electrical circuits within interior walls and decoration structures. Alerts: combined visual indicators and acoustic warnings for clear detection feedback. Principle: detection based on frequency fluctuation caused by changes in material density. Technical specifications (performance examples) Wood detection: for a wood piece sized 30×30 mm, the maximum detection depth is up to 18 mm below a uniform object. Metal detection: for iron pipes with a diameter of 25 mm, the maximum detection depth is up to 30 mm. Compatibility and intended use Designed for use in interior decoration structures and on walls where locating studs, pipes and wiring is required. Suited for both professional tradespeople and home users performing installations, repairs or renovations. Practical use scenarios Installing wall-mounted TVs, shelves or cabinets: locate studs and avoid hidden pipes or live wiring before drilling or fastening. Running or modifying electrical or plumbing work: find existing metal pipes and live circuits to plan new runs or avoid interference. Renovation and surface work (tiling, plastering, cutting): map out concealed wood and metal so you can remove or alter surfaces safely. Usage tip Move the device slowly across the surface and follow the visual and acoustic cues to mark the edges and center of detected objects for accurate placement.
