Why you need this stud detector Avoid damaging hidden wiring, pipes, or studs when drilling or mounting. Locate framing, metal, and live AC quickly and reliably so installations are safer and faster. Reduce guesswork on the job and complete tasks with confidence. Key benefits Precise and fast detection: built-in intelligent microprocessor delivers high sensitivity for accurate, rapid identification of wood, metal, pipes, and AC cables hidden in walls. Clear visual and audible guidance: an LCD signal bar shows distance and direction to the target while the unit beeps to confirm location; backlight improves visibility in low light. Live-wire warning for safety: cable warning remains on in stud scan, deep scan, and metal scan modes to alert you to live AC current and help prevent electric shock or damage. Features and specifications 5-in-1 multifunction detection: Wood detection I: up to 1/2 inch (12.7 mm) Wood detection II: up to 1 inch (25.4 mm) Wood detection III: up to 1 1/2 inch (38 mm) Metal detection: up to 2.36 inches (60 mm) AC detection: up to 2 inches (51 mm) LCD display with signal bar and backlight for easy interpretation of distance and direction. Acoustic warning (beep) to confirm target location. Wire warning display that stays active during stud/deep/metal scans to indicate live AC presence. How it solves common problems Prevents accidental drilling into live wires or pipes by alerting you before you cut or fasten. Helps you find studs at multiple depths for secure mounting of heavy items. Detects metal and pipes behind walls so you can route screws and anchors safely. Practical use scenarios Mounting a TV: scan the wall to find studs and check for live AC or pipes before drilling so mounts are anchored securely and safely. Installing bathroom cabinets or mirrors: locate studs and avoid plumbing and hidden wiring when choosing fastener locations. Hanging shelves or picture frames in a garage or workshop: detect metal and wood framing at varying depths to select the right anchors and avoid damage. What makes this unit stand out Multi-depth wood detection and separate metal and AC ranges give clear, depth-specific information for different tasks. Continuous wire warning during key scan modes provides an extra layer of safety when installing electrical fixtures or heavy mounts. Simple visual and audible cues reduce interpretation errors and speed up the locating process. Usage notes Use appropriate scan mode (stud, deep, metal, or AC) for the material and depth you expect. Follow safe drilling and installation practices after locating targets.
