Simple Sensitive 3 Transistors BFO Metal Detector
Pavleski Aug 04,2023
  In this project I will present you a Very Simple "Beat Frequency Oscillator" type of Metal Detector. BFO metal detectors are relatively simple and inexpensive compared to other types of metal detectors. It is one of the simplest and most common types of metal detectors.   The principle of operation is as follows:When a metallic object is in close proximity to the search coil, the beat frequency produced will be different compared to when there is no metal present. This...
