The heart of this diy metal detector circuit is the CS209A IC. The metal detector is built with one 100µH coil that has 40 mm in diameter and is made of 50 turns/0.4 mm wire. CS209A has one oscillator wich forms a LC circuit, the inductance of the coil will change when it is near metal objects. LED 1 will light up and the buzzer turns ON when ...

1) Using a Single UJT. The first metal detector circuit shown below is perhaps the simplest one you can get. It uses a single UJT device configured as a relaxation oscillator circuit. The circuit looks like an ordinary UJT oscillator without the search coil, however the circuit gets transformed into a metal detector due to the insertion of the ...

100 MHz RF Detector. This circuit is capable of detecting signals up to 100 MHz, depending on the value of L1. Use a 100 µH choke for signals between 30 and 100 MHz, a 1000 µH choke for frequencies between 2 and 30 MHz, and a 2.5 µH choke for signals below 3 MHz. In the circuit, the FET serves as a wideband amplifier.

Setting up the Metal Detector is very simple: - First we need to place the two windings so that the gap between them is the smallest and the variable capacitor is in the middle position. - A very high frequency tone is now heard on the handset. - Next we need to gradually increase the overlap, reducing the frequency of the sound in the handset.

Those seeking gold can choose between VLF circuits with high sensitivity or Pulse Induction PI detector circuits, which use a pulse generator to create the signal in a series of pulses. As the reflected pulse is sent back to the receiver, the gold detector provides an alert sound. Garrett metal detectors produce models in both classes.
