So I cannot tell you how to build a BFO detector.
But I can show you the circuit for a BFO detector that uses coils to work with magnetic signals.
See here for the complete schematic: http://www.geotech1.com/forums/showp...7&postcount=15
The person who posted this BFO circuit is maikl.
You can ask him for help to tell how it works.
You can also ask Mikebg for help. Check here to read all details: http://www.geotech1.com/forums/showt...883#post116883
I do not know if this metal locator works because I never used a BFO metal locator.
You will need to ask the people who posted the circuit.

But,is possible to connect one BFO to one ION DETECTOR,i already do this and it works,even with very good amplification of the BFO signal.
