Wall Scanner Sensor — fast, reliable detection for safer drilling, cutting and mounting What this tool does and why you need it Quickly locates bolts and metal, detects hidden metal objects, and warns you about live AC cables so you can avoid costly mistakes and safety hazards. Designed for fast, efficient scans that save time on installation, renovation and repair tasks. Key features Three scan modes: Auto-Scan, Metal-Scan, and Live AC-Scan to match the detection task you need. Bright graphical LCD with backlight shows mode, detection strength and other status information for clear, at-a-glance feedback. Large detection ring with color signals: green = no object detected, orange = object nearby, red = object within sensor range. 100 mm Auto-Scan capability: measures metal behind drywall, PVC water pipes and AC conductors; in Auto mode the unit prioritizes metal detection over other materials. Center finder with audio confirmation: press the power button to engage an acoustic signal that pinpoints the center of a detected object for precise marking. Built for practical use on common building materials: drywall, PVC piping and standard AC wiring. How it stands out Combines metal, pipe and live AC detection in one handheld sensor so you don’t need multiple tools. Clear visual and audible feedback reduces guesswork and helps you make safer decisions on the job. Simple mode selection and a center finder speed up repetitive tasks and improve accuracy. Typical use scenarios Installing shelves, cabinets or TV mounts: locate studs and avoid hidden bolts, pipes or live wires before drilling. Renovation and plumbing work: detect PVC water pipes and metal fasteners behind drywall to prevent accidental damage. Electrical and maintenance checks: scan walls for live AC cables before cutting or nailing to reduce electrocution risk. Specifications and operation notes Modes: Auto-Scan, Metal-Scan, Live AC-Scan. Display: illuminated graphic LCD for mode and detection strength. Detection indicator: color ring (green/orange/red) for distance/strength feedback. Auto-Scan measurement: 100 mm scanning capability for metal under drywall, PVC pipes and AC conductors. Center finder: audio detection activated via the power button to mark the midpoint of detected objects. Practical, clear and safety-oriented — this Wall Scanner Sensor is designed to help professionals and DIYers make accurate, confident decisions before drilling, cutting or fastening.
