1. Precise MultiLayer Scanning: Multilayer scanning technology achieves the measurement accuracy in detecting wall structures. Automatic surface calibration ensures reliable results with only 0.5 cm deviation tolerance—ideal for precise stud detection in various wall types like drywall or wood paneling. 2. TimeSaving Design: Simplified operation with instantready calibration—two working modes (Standard/Deep Scan) support efficient work without prior knowledge on all common wall types. 3. Hazard Alert System: Gradually intensifying alarm sound with synchronized LED flashing enables precise detection of metal objects and hollow walls even in lowlight conditions through automatic light adjustment. 4. Wide Application Range: Combines multifunctional detection technology for electrical wiring, metal pipes, and steel studs with easy handling, allowing efficient tracing of hidden installations during renovation work.
