Artwork: The Metalloscope patented by Gerhard Fischer (Fisher) in 1937, which I have colored to really make it easier to comply with. The transmitter coil is within the purple box in the entrance; the receiver coil is in the blue box for the back again. The transmitter works by using inaudible thirty,000 Hz signals; the receiver sends out audible indicators (with a frequency of about 500 Hz) to headphones, as in a modern metal detector.
The sensor might be possibly a individual ingredient that may be linked to a metal detector unit or built-in in to the detector alone.
Detection of mines can be achieved by a specially designed metal detector tuned to detect mines and bombs.
