To come up against an electric cable while drilling a hole in a wall can have catastrophic consequences. Likewise, drilling into gas, water pipes or central heating pipes can be extremely hazardous.

With a handy metal detector it can now be determined beforehand whether there are metal objects to be found in a wall, ceiling or floor. An LED indicates if a metal object is in the vicinity. If an audio signal is also desired, space has been provided on the PCB for buzzer type SV4/12-S to be connected. The PCB has been specially constructed to fit entirely into to the separately available box type G407.

•Hints:

?If you experience difficulties with the calibration of the unit (ie if the LED doesn't turn off, when there isn't any metal present ), replace C1 with a ceramic 1.2nF (122) capacitor. This behaviour is due to a spread on the component values and differences created when winding the coils.

?For those wanting an audible signal, space is provided on the print for connecting a buzzer type SV4/12-S. The small PCB has been specially designed to be incorporated into the separately available casing type G407.
