The foundational work by Overton and Moreland breaks down the seemingly magical process of finding hidden treasure into tangible physics. At its heart, a metal detector operates by establishing an alternating electromagnetic field. The foundational principles detailed in the book are

The foundational principles detailed in the book are heavily discussed and expanded upon across the web. The Geotech Community Hub The schematic is drawn in classic

: Readers can find schematics and instructions for building devices like an off-resonance pinpointer , a GEB-discriminator , and even a microprocessor-controlled PI detector .

The book provides an in-depth analysis of the primary technologies that drive modern detectors, covering:
