No need for a back-and-forth motion because it scans as soon as it’s on the wall or surface. Detector is easy to use in small spaces and features an ergonomic design. Because the Bosch D-tect 120 never needs calibration, you can focus on the job without worrying about the detector. Three modes ‒ studs, universal and concrete ‒ make this the right detector for more jobs. Device offers sound with light to show user when something is detected behind a wall, panel or under flooring.
