For those downloading the supplemental files or reading the text, the book focuses on building functional machines, such as: A classic VLF (Very Low Frequency) design. The Sand Shark: A robust pulse induction project.
"Inside the Metal Detector" isn't just a manual; it’s a masterclass in electromagnetic theory and practical application. If you are serious about building your own high-performance machine or simply want to understand the "magic" inside your commercial detector, this text is an indispensable part of your library.
The authors are the driving force behind , the world’s leading community for metal detector design. If you are looking for the "updates" mentioned in the book's later printings, the Geotech forums host the most current discussions on part substitutions (as some older ICs become obsolete) and software tweaks for the book's featured projects [5].
