This is a great detection tool for plumbers and installers, or for anyone who wants to boost their day to day efficiency whilst reducing the risk of drilling into unknown areas. With three surface material modes; Drywall, Metal and Live wire, switching between these based on the wall material will optimise your detection results. The GMS 120 has a max detection depth of 120mm and can detect ferrous and non-ferrous metals, wooden studs and even live wires that are hidden behind a wall.
