Just wondering if anyone out there has constucted this metal detector and if it works well. I've taken a look at the schematics and think that it should be easy to make.

This was probably a good detector in 1985, but today?????
Unfortunately it has a VCO audio output (of which I'm not a big fan). The initial setup is also quite laborious, and it has that annoying feature where the meter needle gives a "shadow" response to some targets. There have been other much better designs posted on this forum.
