Four detection modes provide versatility for different applications. The device can identify wood or bolts at depths up to 13 mm with the 1/2 bolt scan mode, 25 mm with the 2.5 cm mode, and 38 mm with the 1-1/2 inch mode. It detects magnetic metals up to 80 mm deep and non-magnetic metals up to 60 mm deep. Accurate depth readout is displayed on a green backlit screen, offering clear visibility for precise measurements and reliable locating in all lighting conditions. Wide surface compatibility ensures the locator works on plaster, wooden floors, acoustic ceilings, and painted walls. It is suitable for both home use and professional environments. Enhanced safety is provided by the AC mode function, which identifies live unshielded AC cables. This helps you work safely when installing devices such as televisions or cabinets, reducing the risk of electrical accidents. Use scenarios - Wall mounting a television or heavy shelf: locate studs and check for hidden electrical cables before drilling. - Installing kitchen or bathroom cabinets: find studs for secure mounting and verify there are no live wires behind the wall. - Renovation or drywall work: scan plaster or painted walls to identify studs and detect metal before cutting or drilling, using AC mode to check for live cables.
