The creation of "Inside the Metal Detector" was a story of parallel efforts. George Overton and Carl Moreland independently realized there was a critical gap in published literature. While many books existed on how to use a detector or on specific types of finds like coins, there was a complete lack of detailed information on the electronics and physics that make a detector work. As both were working on their own manuscripts to fill this void, they discovered each other's efforts. Surprisingly, there was very little overlap in their separate compilations; Overton’s strengths lay in BFO (Beat Frequency Oscillator), TR (Transmit-Receive), and VLF (Very Low Frequency) designs, while Moreland’s focus was on PI (Pulse Induction) technology. This complementary expertise allowed them to combine their work into a single, comprehensive volume.

The book breaks away from traditional "how-to-hunt" guides. Instead, it systematically breaks down the electromagnetic physics and signal processing techniques that govern how a detector interacts with sub-surface metallic targets.
The simplest topology utilizes two distinct high-frequency oscillators. A fixed internal reference oscillator beats against a search loop oscillator . When the search coil passes near target metal, the change in the loop's inductance shifts its operating frequency. The mixed difference between these frequencies generates an audible audio tone.
The textbook breaks down the behavior of these targets based on two fundamental physical properties:
The PDF of "Inside the Metal Detector" is a true landmark in technical publishing.

Moreland’s role as the Engineering Manager at White's Electronics and, later, First Texas, brought a vital industry perspective to the book. His academic credentials include a Master's degree in Electrical Engineering from Florida State University, followed by an 18-year career at Analog Devices designing integrated circuits for high-speed ADCs and op-amps. This background in precision analog design is evident throughout the book's technical sections. Moreland's personal projects, like the "Hammerhead" pulse induction metal detector , provided a practical platform for experimenters to learn PI technology, a design that is closely mirrored in the book's projects. His numerous patents, covering multi-frequency platforms and motion sensors for metal detectors, further underscore his role as a leading innovator in the field.
