The book breaks down the fundamental principles of how targets respond to electromagnetic fields.
While the book is "crammed with digital schemes of circuits" and aimed primarily at builders, it is also highly useful for serious detectorists who want to understand their equipment's controls and target responses.
"Inside the Metal Detector" by George Overton and Carl Moreland is an essential guide for anyone interested in metal detecting. Whether you're just starting out or have years of experience, this book offers a wealth of information to enhance your hobby. The comprehensive coverage, coupled with the practical advice and insights into advanced technologies, makes it a valuable resource.
A commercial detector costs $200–$2,000. The parts for the "Overton IB" detector cost roughly $30 (excluding the coil). For educators and students, this PDF is a goldmine for teaching applied electromagnetism. The book breaks down the fundamental principles of
The authority of the book stems directly from its creators. George Overton and Carl Moreland are the masterminds and administrators behind the Geotech Forums , the internet’s largest open-source depository for technical metal detector research.
, authored by George Overton and Carl Moreland , is widely considered the definitive technical guide to the engineering and physics behind modern detection systems. First published in 2012 by Geotech Press , the book fills a massive void in technical literature, serving as the first in-depth exploration of the field since the late 1920s.

: The book starts with the fundamentals, explaining the theory behind metal detectors, including how they detect metal, the types of detectors available (e.g., Very Low Frequency (VLF), Pulse Induction (PI)), and the differences between them. This foundational knowledge is crucial for both beginners and seasoned detectorists looking to upgrade or understand their machines better.
The answer lies in the philosophy of the PDF. Overton and Moreland were not trying to compete with commercial manufacturers. They were trying to . The parts for the "Overton IB" detector cost
A highlight of the work is its inclusion of working example designs and experiments, allowing readers to build their own equipment: . GEB-discriminators . Microprocessor-controlled PI detectors . Editions and Availability
Build an off-resonance pinpointer for precise target location.
One of the most valuable aspects of the work is its emphasis on practical application. The book is filled with "hands-on" experiments and complete DIY projects for almost every category of detector.
and Carl Moreland are not just writers; they are practitioners of the science. Their combined expertise in electronics and physics provides a trustworthy foundation, making this book a staple in the detectorist community. Conclusion
