Greetings from mother Russia to all fellow treasure hunters. I have been into relics hunt for quite some time now in the wast 😉 wilderness of cold weather and hot drinks ) Coming to the same conclusion about analogue technology in MD was a revelation that has happened just a few weeks ago. Not satisfied with modern DD offerings I started building my own coils researching and reading russsian forums when I found a very wery 😅 promising design of square wave PI machine on md4u.ru. The detector recuperates the energy and hops through many loops with ultra professional analogue design. On the point of discussion here, the engineer who created the marvel MD comments that he refrained from using digital ics and blocks only because of the common sense, - if he was to use integrated circuits, it would either cost on power consumption or weight or signal resolution or combination of all these plus a number of other factors. As I gathered, this is the most sofisticated diy project and, to my mind, most advanced discrimation technology invented. Astounding one man show that can take on competition of Minelab and its latest GPZ (also uses square wave PI). The invention is currently tested with ferrite core rod in the search head. With certain improvements this type of device can test ground several meters with very little effect from any difficult soil types (another advantage of the design).
