Hidden rebar, pipes, wires and wood have met their match, boasts Bosch, with the new GMS 120 wall scanner. The scanner is able to detect both ferrous (magnetic) and non-ferrous (non-magnetic) metals, wood studs and live AC wires. The straightforward, ergonomic hand tool features single-button operation; simply select a mode (wood, metal or live AC wiring) and scan the surface to find objects behind the wall or in concrete. (All modes can detect live wires and provide a live wire warning.) The GMS 120 is always calibrated in metal and live wire modes, says Bosch. For wood mode, it automatically calibrates when the tool is placed on the wall. After the initial calibration, the GMS 120 automatically calibrates after 30 seconds every 10 seconds. Then between 30-60 seconds, the tool automatically calibrates every 15 seconds. At over a minute, the GMS120 routinely calibrates every 30 seconds. The tool’s large LCD display shows the location of an object’s depth, width and edge.
