About this product
The Bosch GMS 120-27 Professional is a wall scanner for detecting metals (magnetic and non-magnetic), live wires, and wooden studs behind drywalls before drilling. It is aimed at tradespeople carrying out renovation work such as fitting cabinets, kitchen units, or installing HVAC and sprinkler systems.
Results are shown via signal indication on the display, with a colour-coded marking hole allowing objects to be marked precisely once found. Operation is kept simple with straightforward mode selection.
Built for job-site use, it has IP54 protection against dust and splash water plus a shock-absorbing rubber casing. Maximum detection depth is 120mm overall, with up to 100mm for magnetic metal, 120mm for non-magnetic metal, 50mm for live cables, and 30mm for wooden substructures. It weighs approximately 0.29kg and is supplied with a pouch and 2 x 1.5V AA batteries.
