The FAIDET31 advanced electronic detector can be used to detect and locate wooded studwork, metal and AC voltage, providing a clear indication of concealed objects using the LED and buzzer indicator system. This helps avoid costly mistakes caused by drilling into concealed power cables, gas or water pipes and removes any guesswork when securing fixtures, hanging pictures or fitting shelving by pinpointing a solid base for fixing. A marking groove is also provided at the top of the detector so that the surface can be marked prior to any drilling, nailing or screwdriving.
