With this handy Velleman Metal Detector Kit you can find out before drilling whether there are metal objects to be found in a wall, ceiling or floor, so avoiding the potentially catastrophic consequences of drilling into gas or water pipes or through an electric cable. An LED indicates if there is a metal object in the vicinity, giving you peace of mind when you start repair or decoration work. If an audio signal is also desired, space has been provided on the PCB for a buzzer.
