Drilling through a plumbing pipe is very stressful and requires chiseling the wall to repair the leak. Drilling through a live wire however not only damages the electrical system but also poses a high risk of electric shock and loss of health or life. Using the cable and profile detector you speed up your work and at the same time ensure your safety.the dedra mc0962 cable and profile detector allows you to detect metal elements and profiles electrical cables with and without ac voltage and wood. This helps to supplement the technical documentation of buildings. The high-sensitivity sensor and clear display allow for more precise location of the desired element minimizing the risk of drilling through a pipe or bundle. Electrical. Additionally the wire detector has an audible signal so you don't miss any alerts. The set includes a case a belt clip and an instruction manual.features of the mc0962 wire and profile detector:easy-to-read backlit white 2 led screendiodes signaling the detection of the searched material in 3 colors: green/yellow/redaudible signalautomatic shut-off after 5 minutes of inactivitydetects profiles pipes and wires with and without ac voltagerubberized housing elements improve gripcomfortable case and belt cliphigh sensitivity and central locationpercentage indicator**
