If you can’t locate it, reply and I can describe the or key circuits from the book, or help you find alternative resources for building/understanding metal detectors.
The original Overton manuscript (circa 1998) was typewritten, with hand-drawn schematics. Carl Moreland’s first revision (early 2000s) cleaned it up but was still based on analog parts like the LM308, NE5534, and 2N3904 transistors. The community has since scattered "updates" across forum threads—new coil balancing methods, differential PI mods, and microcontroller integration.
