Bosch D-tect 150 - 150 mm Professional Digital Depth Detector provides the user with the technical data like detectable materials, e.g. plastic pipes, ferrous metals, non-ferrous metals, etc. Bosch D-tect 150 CNT has the measurement depth of the 150mm detection depth, steel, max. 150 mm accuracy. It has a digital display of material properties and maximum permitted drilling depth. Professional Digital Depth Detector has a future technology of detection. It is well known for the precision of the highest order ultra wideband radar sensor system for material detection of ferrous metals, live cables, wooden beams, plastic pipes, etc. Bosch Digital Depth Detector has a unique feature of detecting objects more reliably even in damp concrete. It has optimum ease of operation due to an ergonomic handle. It is preferred for precise detection of floor and wall heating system. It also has maximum safety due to display of maximum permitted drilling depth. Five different modes allow the user to have the best possible detection on any surface. It requires no calibration.
