Depth-Optimised 4-in-1 Wall Detection Tool

This wall scanner has dimensions of 13.5 cm × 6.5 cm × 3.2 cm and weighs 180 g. It offers four scanning functions: STUD mode finds wood beams and joists up to 0.75 inches deep in drywall; DEEP mode detects wood and metal up to 1.5 inches deep; METAL mode locates pipes, rebar, aluminium and copper up to 2.36 inches deep; AC mode identifies live wires up to 2.0 inches deep. A large LED screen gives directional guidance, and a clear audible tone indicates object position — changing to distinguish edge from centre. Calibration is automatic and varies by mode: on-wall for STUD and DEEP, in-air for METAL and AC. Power source: 2 × AAA batteries (not included).
