1. Reliable Structure Detection: Combines deep scanning and calibration to detect hidden beams and voids. Achieves precise 0.5 cm measurement accuracy with an adaptive algorithm that automatically adjusts to wall materials like drywall or masonry. 2. Versatile Application: Universal wall scanner for drywall, concrete, and wooden structures with automatic depth detection up to 50 mm, ideal for DIY projects and installation work. 3. Proximity Alert System: Smart warning intensity adjustment detects distance changes to hazards and reliably alerts users to hidden electrical wires or voids through a combination of audible signals and LED flashing, even in dark environments. 4. Wide Range of Uses: Integrates multifunctional detection technology for electrical wiring, metal pipes, and steel beams with easy operation, enabling efficient identification of hidden installations during renovation work.
