A few people have worked out most of the chips on the Minelab SD2000, can others fill in the blanks? The SD2000 is still the deepest detector of the Minelab range. The one thing that im sure is worth modifying is the P & N channel FET front end, the next IC in line that is a matched transistor pair.
All these parts are 10 year old technology and better parts must be available.
