Long Range Metal Detector Circuit Diagram

The metal object has to be at a distance of 10mm for the detector to detect it.

Long range metal detector circuit diagram.

Metal detector circuit diagram the metal detector is a relatively simple device an electronic circuit that provides good sensitivity and stability. Metal detector coil operates at a frequency of 3 khz. A distinctive feature of this device is the low operating frequency. The main disadvantage of this metal detector circuit is the range of detection.

Below is an example of a circuit diagram for a long range gold detector. 2 x 47nf capacitors ceramic capacitor code 473. This is nothing but a colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. The following image shows the circuit diagram for the metal detector circuit.
