Prevent drilling in the wrong places by using the Bosch UniversalDetect. Because the last thing you want is that you will encounter electric wires or iron nails during drilling. With the detector at hand you will be warned by both an acoustic signal and an LED light system when it finds iron, copper, substructures or electrical cables in the wall. He does this to a maximum depth of 10 centimeters. The handy marking aid shows exactly where you drill in a safe place in the wall. The automatic calibration of the UniversalDetect in combination with the step-by-step instructions also makes the digital detector reliable and user-friendly.
