Bosch’s GMS120 digital multi-scanner provides detection of multiple materials, including wood, metal, and live wiring. Because of its versatility and consistent performance, it’s an ideal tool for construction, electricians, contractors, carpenters, masons, plumbers, and others who need reliable detection. With its three modes, Bosch’s GMS120 digital multi-scanner is an aid in most situations, as its modes cover wood studs, metal objects such as rebar, studs, and steel/copper pipes, and live wiring. It has precise automatic calibration that makes use easier and an automatic center finder, which pinpoints the center spot of the wood or material that has been detected. The GMS120 has a deep metal detection feature, which allows a user to detect steel that is placed up to 4-3/4-inches (120 mm) deep in cured concrete. It has a maximum detection depth of up to 2 inches for live wiring, up to 3-1/8 inches for copper, and up to 1-1/2 inches for wood studs.
