3 In 1 Wall Detector
. The wall scanner uses electronic signals to pinpoint the center and edges of objects behind drywall.
. Metal Scan Mode (Up to 76 mm / 3 inches) : Detects ferrous (e.g., iron rebar, steel pipes) and non-ferrous metals (e.g., copper pipes) deep within the wall.
. Wood Scan Mode (Up to 38 mm / 1.5 inches) : Locates the center and margins of structural wooden framing or wall studs.
. AC Live Wire Mode (Up to 76 mm / 3 inches) : Continuously tracks unshielded live electrical voltage wiring to prevent hazards while drilling.
. Hold the device flat against the wall away from any known studs or wires, then press and hold the side scan button until the device finished single-beeping to set the wall's baseline density.
. Slide the tool slowly across the surface horizontally. Keep the scanner flat and do not lift it during use to ensure data precision.
. Battery : 9V
