Inside the Metal Detector George Overton Carl Moreland is widely regarded as the definitive technical guide for understanding, designing, and building metal detection technology. Unlike typical hobbyist guides that focus on how to use a detector, this work dives deep into the engineering and physics of how these devices actually function. Amazon.com Core Technical Concepts
One of the most cherished sections of the PDF is Carl Moreland’s design for a Pulse Induction (PI) detector, specifically the "Surf Pi." Unlike continuous wave detectors, PI detectors send short, powerful bursts of current into the coil and then listen for the decaying echo. Inside the Metal Detector George Overton Carl Moreland
