I'm building and studying metal detectors for more than 15 years and learned a lot of things both from my curiosity and experimentation and also a lot on Geotech forums and so, I've decided to write an eBook about the Metal Detectors Technology without entering in complex technical subjects dedicated for all the metal detectorists that want to know better how their machines work and take advantage of that while searching for treasure or prospecting precious metals. You can download it in Amazon for a very affordable price. Here are the links: English version (Metal Detectors Made Simple: The Technology Behind Treasure Hunt): https://www.amazon.com/dp/B0FT2173T3 Portuguese version (Detectores de Metais Descomplicados: A Tecnologia por trás da caça aos Tesouros): https://www.amazon.com.br/dp/B0FSC448WC Any suggestions, leave your comments!
DYI and homemade lover. Making things by ourselves gives us pleasure and it can be useful for so many everyday life tasks.
