A Very Simple `Beat Frequency Oscillator` type of Metal Detector.These are about the Simplest of all Metal Detector types,But still quite useful for many Detecting applications.And although this one is particularly simple, I find it works very well. visit page.Simple BFO Metal Detector - schematic

If there is Enough Interest in this Project, I will create a PCB for it and Elaborate on the coil Construction. But for now, Only the Schematic is Presented here. L1 is a Standard RF Choke. My choke was made by "Delivan", and I can supply th
