A single coil serving as both transmitter and receiver (primarily for PI systems).

Unlike continuous-wave VLF units, PI systems use time-domain processing rather than frequency shifts.

The book methodically breaks down the technology into digestible sections. It moves from basic principles to advanced concepts.

Projects for GEB-discriminators and VLF-discrimination circuits. A single coil serving as both transmitter and

The book begins by establishing the physical foundations of electromagnetism that dictate how a metal detector interacts with subterranean environments. Rather than treating the ground as an inert medium, Overton and Moreland detail the challenging physics of .

Unlike hobbyist manuals that focus on how to find treasure, this work explains how the hardware actually functions. It is primarily targeted at: It moves from basic principles to advanced concepts

While the book is "crammed with digital schemes of circuits" and aimed primarily at builders, it is also highly useful for serious detectorists who want to understand their equipment's controls and target responses.

This is where the magic happens. Immediately after the transmit pulse shuts off, the coil generates a reflected voltage from the ground. Overton’s circuits use an ultra-fast switching diode (like the 1N4148 or BAT41) to clamp the incoming signal. Rather than treating the ground as an inert

The guide explores several distinct ways to build a metal detector, each with its own pros and cons:
