Metal Detector Circuit Diagrams

We've found a few metal detector circuit diagrams that we think are really cool. Happy metal detecting and treasure hunting.

Gary's Pulse Induction Metal Detector
Lots of information about this metal detector. Features a full circuit diagram, a PCB (Printed Circuit Board), photo's of the metal detector kit assembled by people using the design, design problems and workarounds, metal detector coil winding information, etc.

Super-Heterodyning Metal Detector Circuit
Based on the principle of "Superheterodyning" (used in Superhet receivers), the frequencies of 2 RF oscillators are fixed at 5.5 MHz. Circuit operation and metal detecting information is included on the page. No PCB is given, though it should be an interesting challenge to build it regardless.
