Long distance Metal Detector schematic | Forum for Electronics

Detecting an engine block at 30cm should not be too difficult, but reliably detecting a single small nail at 30cm may not even be possible. It probably has more to do with the design of the search coil than the actual circuit how far the magnetic field extends around the search coil.
