V-K7102:Metal Detector Kit, Buzzer Included

To encounter an electric cable when drilling a hole in a wall can have catastrophic consequences. Likewise to drill into water pipes or central heating pipes can cause major problems. That is to say nothing of course if one has the misfortune to drill into a gas pipe. Now with a handy metal detector it is possible to check for metal objects in and behind walls, floors and ceilings. An LED turns on if the detector comes into the vicinity of metal objects.
