Very little is publicly known about George Overton—a quiet genius who preferred circuit diagrams to self-promotion. In the late 1990s and early 2000s, Overton authored Inside the Metal Detector , a manuscript that broke down the physics and electronics of induction balance (IB) detectors, very low frequency (VLF) designs, and pulse induction (PI) machines. Unlike dry engineering textbooks, Overton wrote with the hobbyist in mind, using oscilloscope screenshots, coil formulas, and practical troubleshooting. Amazon
