Thanks for sharing, I have also built the LC meter. It works very well.

On the howstuffworks website there is a good explanation of pulse induction detectors. We need to look at the decay of the coils pulse. This will indicate what kind of metal is buried.

I'm going over the schematic and thinking you could free up your ADCs and PWMs if you used an i2c connection for the LCD. Of course I didn't see any C code to help figure out what he's doing though.
