    • 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 SV8. The small PCB has been specially designed to be incorporated into the separately available casing type G407.
