The precise drilling guide consists of a transmitter and a receiver, allowing for the safe alignment of the drill channel for wall and ceiling drilling up to 150 cm. Location is indicated by easily visible LED indicators and acoustic signals. Well-accessible marking aids in both the transmitter and receiver assist with center alignment. The integrated LCD display can determine the required drilling depth of up to 200 cm. The TX transmitter with metal and voltage detection ensures effective prevention of misdrilling. An optical and acoustic warning is emitted when foreign objects are detected. The simple and accurate alignment of the drill channel, as well as the precise location of entry and exit points, is achieved through the LED indicators.
