more? Then this one may be exactly what you're looking for.
The metal detector circuit shown here must represent the limits of simplicity for a
metal detector, yet the design works surprisingly well. It uses just on.
How metal detectors work - short theory and example circuits for VLF (Very Low
Frequency), PI (Pulse Induction) and BFO detectors.
The Simplest Metal Detector Circuit is also shown below and it only requires 4
components. Using a Faraday Shield around the search coil will reduce the effect
