First and foremost refer to my post if you scroll down to CZ3D in laymans terms which should help you out...
Second it was originally made by the old Fisher and is continuing to be made by the new Fisher.
Third depending on you hunting areas you could be missing old nickles such as Buffalo, V, and shield as they may come in foil on your CZ5. Also with your CZ5 in Zinc you could be missing a lot of old coins which I have mentioned but have to add real old indian head pennies which would come in square tab and a large 10kt gold ring which I omitted from my original post.
CZ3D is basically the same machine rel depth with new meter parameters where you basically dig all high tones when in old old areas to catch all the old coins along with junk(basically dig more to find more) and a flip of the toggle to the left and you have basically a CZ5 so in actuallity its two units in one with the flip of a toggle. Left for new areas, right for old areas. Could you find the same items with a CZ5 in old areas I would think so but you would have to dig foil and square tab along with nickle, Zinc and the last facet coins all and in doing so so would also dig a whole lot of junk as Nasa Tom's principles have basically been incorporated in the CZ3D to catch all the old coins with meter changes digging all high tones and cutting down the junk dug..
