Bfo Metal Detector: 6 Steps Simple BFO metal detector BFO ( beat frequency oscillator ) metal detectors use two oscillators, each of which produces a radio frequency. One of these oscillators uses a coil of wire that we call the search loop. The second oscillator uses a much smaller coil of wire, and is usually inside the control box and is called the reference oscillator. BFO Metal Detector (Beat Frequency Oscillator) The oscillators in this circuit operate just below the bottom end of the AM Broadcast Band at a frequency of 494 KHZ. Although this is a bit high for a BFO metal detector, it allows for the finding of very small objects such as small rings and coins. How it Works: One JFET oscillator working with the search coil operates around 494 KHZ. Metal Detector Circuit using a Single IC Simple metal detector circuit.
