, co-authored by George Overton and Carl Moreland , is widely considered the definitive technical reference for anyone interested in the science and engineering of metal detection. Rather than a simple "how-to" guide for treasure hunting, this book offers a deep dive into the electronics, physics, and circuitry that allow these devices to find buried objects. Core Technology and Concepts

The latest editions include sections on multi-frequency techniques, Phase-Locked Loops (PLL), and hybrid digital methods. For Designers and DIY Builders

There are multiple versions of the book, with significant differences between them: Go to product viewer dialog for this item. Inside the Metal Detector

The authors provide an exhaustive breakdown of the primary technologies used in modern detection, moving from historical principles to advanced digital techniques.

Details include ground balance methods and advanced PI techniques often used for deep seeking and gold prospecting.

Detailed instructions on are also included, explaining how different coil types (like Concentric and Double-D) compare in terms of performance and depth. editions and availability
