- Purpose: This wall scanning device helps with interior work by locating metals, wood, and live electrical circuits behind walls. It provides visual indicators and audible alerts when targets are detected. - How it works: It detects changes in material density beneath the sensing area, causing frequency shifts in the detector to identify hidden materials. - Depth performance: Wood detection depth up to 18 mm for a 30 by 30 mm area under a uniform object. Metal detection depth up to 30 mm for iron pipes with a diameter of 25 mm. - Practical benefits: Reduces guesswork when mounting fixtures, prevents drilling into wires or pipes, and improves planning and safety for renovations and installations. - Use scenarios: - Before drilling for electrical outlets or switches to locate live circuits. - Mounting shelves, cabinets, or a TV to avoid hidden studs or conduits. - Renovating a room and mapping wall composition to decide where to cut or fasten. - Why it matters: Clear indicators and fast alerts help you work more efficiently, accurately identify hidden materials, and reduce the risk of damage during interior projects.
