Inside The Metal Detector George Overton Carl Morelandpdf !link! Full Jun 2026

Master the basics of coil winding, frequency stability, and basic audio amplification.

A seasoned electronics engineer and developer of the popular Geotech website, a hub for DIY metal detector builders. Master the basics of coil winding, frequency stability,

The core value of the book lies in its ability to translate abstract electromagnetic theory into tangible engineering reality. For the uninitiated, a metal detector appears to operate on near-magic: a sweep of a coil results in a beep. However, Overton and Moreland meticulously peel back the plastic casing to reveal the intricate dance of electromagnetic fields. The authors provide a deep dive into the fundamental principles of electromagnetism, specifically how a transmitter coil generates a primary magnetic field and how a receiver coil detects the secondary field emitted by a conductive target. They do not shy away from the mathematics, offering readers the necessary formulas to understand inductance, capacitance, and the crucial concept of phase shift—the characteristic that allows detectors to discriminate between a rusted nail and a silver coin. For the uninitiated, a metal detector appears to
