Reliable structure scan: depth sensing and calibration work together to detect hidden studs and voids. 0.5 cm precision is achieved with an adaptive algorithm that automatically adjusts to wall materials such as plasterboard or masonry. Intuitive technology: self-calibrating system with optical and signal cues guarantees precise results when locating studs and electrical lines, including a non-slip grip zone for safe operation. Adaptive alarm levels: warning signal intensity automatically adjusts based on detection distance. Dual-sensor technology provides accurate distance measurement to help prevent accidental drilling into live wires. Broad versatility: combines multifunction detection for electrical lines, metal pipes, and steel beams with easy handling, enabling efficient identification of hidden installations during renovations. Use scenarios: - Mounting a wall cabinet or shelf: locate studs and avoid electrical lines. - Renovating a kitchen or bathroom: map cables and pipes before drilling. - Installing heavy fixtures: find steel beams behind walls or ceilings for secure anchoring.
