Bosch GMS 100-23 Multi-Material Detector
The Bosch GMS 100-23 Professional Multi-Material Detector is a reliable wall scanner designed to help professionals detect ferrous metals, non-ferrous metals, and live electrical wires before drilling, cutting, or installing fixtures. Ideal for electricians, plumbers, HVAC installers, carpenters, and renovation contractors, it improves jobsite safety by identifying hidden objects behind walls, ceilings, and floors.
With a maximum detection depth of 100 mm, the GMS 100-23 accurately locates hidden metal objects and live cables while clearly identifying the object type using intuitive LED indicators. The detector features single-mode operation, making it easy to use even for first-time users, while the integrated marking hole allows precise marking of detected object locations without moving the tool.
Built for demanding construction environments, the GMS 100-23 features a rugged IP54-rated housing with a shock-absorbing rubber casing for enhanced durability against dust, splashes, and accidental drops. It is powered by either the Bosch BA 3.7V Li-Ion battery or standard AA batteries, providing flexibility for professionals working on site.
