Model HW710 Stud, Metal, and AC Wire Detector Overview The HW710 locates wood studs, metal objects, and unshielded live AC wires hidden in walls, floors, and ceilings. Compact and simple to use, it helps you avoid hitting structural members or live wiring when mounting televisions, shelves, cabinets, or garage racks. Key benefits Multimode detection in one tool: stud mode, metal mode, and AC mode for fast, reliable locating of common hidden objects. Selectable stud depths let you match the scanning mode to the wall thickness for improved detection. Works through a variety of surface coverings including flat surfaces, wallpaper, wood floors, acoustic ceilings, and spraypainted walls. Portable and battery powered for onsite use; uses a standard 9V battery 6F22 (not included). Specifications Model: HW710 Packaging size: 174 x 76 x 41 mm Weight: 170GB Battery: 9V battery 6F22 (not included) Detection modes and performance Stud Mode: Three scan depth options to suit different surface thicknesses: 1/2 inch scan mode detects up to 1/2 in (13 mm) deep. 1 inch scan mode detects up to 1 in (25 mm) deep. 1 1/2 inch scan mode detects up to 1 1/2 in (38 mm) deep. If depth is unknown, begin with 1/2 inch mode and switch to deeper modes if needed. Metal Mode: Detects magnetic metal up to 3.2 in (80 mm) deep (example: diameter 15 mm galvanized steel tube). Detects nonmagnetic metal up to 2.4 in (60 mm) deep (example: diameter 13 mm copper tube). AC Mode: Detects unshielded live AC wiring up to 2 in (51 mm) deep. Practical applications Mounting a flatscreen television: find stud centers to secure the mounting bracket and scan for live wires before drilling. Installing cabinets or shelving: locate studs for secure fastenings and confirm there are no hidden metal pipes or live wires in the attachment area. Renovation and finishing work: check behind plaster, drywall, wallpaper, or spraypainted surfaces to avoid damaging hidden utilities. What to expect in use Simple mode selection and scanning make the HW710 suitable for both DIY homeowners and professional installers. Begin scanning with the shallow stud mode when surface thickness is unknown; use deeper modes as required. Keep in mind detection depths depend on object size, material, and orientation; follow the guidance above for results.
