Overton and Moreland explained, often with hand-drawn diagrams and accessible math, that a metal object reacts to a magnetic field by shifting the phase of the returned signal. Inside The Metal Detector George Overton Carl Moreland.pdf

It mixes two radio frequencies to create an audible beat note that changes pitch when metal is nearby. Inside the Metal Detector by George Overton and

A metal detector consists of three main components: Inside the Metal Detector: Moreland, Carl - Amazon

BFO is the simplest form of metal detection, often used in entry-level kits or hand-held pinpointers.

The detector sends powerful, short pulses of current through a single coil. Each pulse generates a magnetic field. When the pulse ends, the field collapses, creating a voltage spike. If metal is nearby, the eddy currents inside the metal delay the decay of this voltage spike.

"Inside The Metal Detector" by George Overton and Carl Moreland serves as a comprehensive technical guide to the engineering, circuitry, and operating principles of metal detection, tailored for builders and engineers. The text covers major topologies—including VLF and Pulse Induction—and features practical, hands-on projects, with the 3rd edition offering significantly expanded, updated content.
