Key Features of Bosch GMS 120 Professional Multi Material Scanner
Consistent Material Coverage
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.
Deep Detection
The Bosch 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.
User-Friendly Features
Bosch’s GMS 120 digital multi-scanner provides an illuminated ring that indicates detection status and an audible detection signal with an on/off button. Adding to the user-focused design, its bright and readable illuminated graphical LCD display indicates mode, detection strength, and more, making it simple to check the detection device and switch modes and tasks. In addition, its ergonomic soft-grip provides a comfortable grip that’s secure and safe.
