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. Accurate Detection: Dual sensitivity modes enable reliable detection of wooden studs and metal behind plaster/cement boards, for renovation work on walls of varying thicknesses thanks to smart measurement technology. 3. Proximity Alarm System: Intelligent warning intensity adjustment detects distance changes to hazards and alerts users via combined audio signals and LED flashes, even in dark rooms, effectively warning of hidden live wires or cavities. 4. Wide Application Range: Combines multifunctional detection technology for electrical wiring, metal pipes, and steel beams with easy operation, enabling efficient tracing of hidden installations during renovation projects.
