Stud Finder wall scanner — precise, reliable detection for safer, faster wall work Key benefits Reliable multi-sensor detection: Advanced multi-sensor technology locates stud edges, stud centers and live AC cables quickly and accurately to reduce guesswork and avoid costly mistakes. Clear, actionable feedback: The bright display shows distance, detection signal strength and stud center so you know exactly where to drill or anchor. Versatile 7-function operation: Switch between seven detection modes — edge, center, metal, wood, magnetic, live AC cable and scan mode — to match the task and get comprehensive coverage. Fast setup and interference resistance: Automatic calibration makes scanning quick and trouble-free, minimizing false readings caused by nails, nearby power cords or metal objects. Easier projects and fewer surprises: Detect metal, wood, magnetic targets and live wiring with one tool to protect wiring and hardware behind walls. What it does Finds stud edges and centers for accurate mounting of shelves, cabinets, mirrors and TVs. Detects live AC cables to help avoid electrical hazards while drilling. Locates metal and magnetic objects that can affect anchors or signal the presence of pipes, conduit or fasteners. Scan mode gives broad wall coverage for faster surveying before cutting or drilling. How to use Press the automatic calibration button to begin a scan. Move the scanner slowly across the wall; monitor the display for distance, signal strength and center indicators. Switch between the seven functions to confirm material type or to verify live wiring before you cut or drill. Practical applications Mounting a TV or heavy shelf: Find the stud center for secure anchors and confirm there are no live AC cables behind the mounting zone. Hanging mirrors, cabinets or artwork: Identify stud edges and centers to place screws in solid wood rather than drywall alone. Renovation and wiring checks: Scan walls to locate metal pipes, conduit or hidden fasteners, and to avoid live AC cables when planning electrical or plumbing work. Performance and reliability Multi-sensor scanning ensures consistent, repeatable readings across typical wall builds. Clear distance and signal strength readouts reduce uncertainty and speed decision-making. Automatic calibration reduces false positives from nails, cords or nearby metal. Includes functions for detecting stud edges, stud centers, metal, wood, magnetic targets, live AC cables and a scan mode for full-wall coverage. Simple controls and clear display make it suitable for pros and DIY users who need dependable, accurate wall scanning.
