Beat Balance Metal Detector

Posted on Feb 5, 2014

Here`s a metal detector circuit that frequencies of the two oscillators are then mixed in similar fashion to BFO, to produce an audible heterodyne. On the surface of it, this design would seem to represent little more than a twinned BFO metal detector. What makes the metal detector different above all else ( check a simple metal detector ), and si

gnificantly increases its range, is that each coil modifies the frequency of the adjacent oscillator through mutual coupling. This introduces the "balance" that is present in an IB metal detector, and boosts sensitivity well beyond that of BFO. Disclaimer All files are found using legitimate search engine techniques.
