Long range metal detector circuit diagram.
The metal object has to be at a distance of 10mm for the detector to detect it.
This is nothing but a colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency.
A distinctive feature of this device is the low operating frequency.
The main disadvantage of this metal detector circuit is the range of detection.
This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket radio.
The following image shows the circuit diagram for the metal detector circuit.
Metal detector coil operates at a frequency of 3 khz.
Below is an example of a circuit diagram for a long range gold detector.
Long rang detector made usa long range device developed to detect gold nuggets and treasure gold after many efforts manufactured and developed to be the first in the world to discover raw and artificial gold caves made in usa terra gold lr 100 is an innovative long range detector for electronic dowsing however only a single frequency preset selection can be made at a time.
