While Overton and Moreland provide the technical deep-dive, the history of metal detection often starts with a high-stakes medical emergency. In , after President James A. Garfield was shot, Alexander Graham Bell hurriedly invented a crude metal detector (an induction balance) to locate the bullet lodged in the President's body.
While I couldn't find concrete evidence of the "Inside the Metal Detector" guide by George Overton and Carl Moreland, the topic highlights the importance of knowledge and guidance in metal detecting. A comprehensive guide can be a valuable resource for enthusiasts, providing expert advice, techniques, and best practices. If you're interested in metal detecting, I encourage you to explore online forums, instructional courses, and reputable guides to improve your skills and enhance your experience.
