Hi Doug,

That is a nice looking circuit setup. When I used to service for the Radio Shack they sold a cheap metal locator. That unit had 2 oscillators that beat against each other to produce a tone. One oscillator had the detector coil as part of its oscillator. If metal came near the external detector coil the inductance would change and the beat frequency would change. It was a simple but effective approach. I am sure the technology has improved since the late 1970s.
