Bryanm362, the detectors you speak of are not suited for regular detecting (coins, relics, jewelry, etc....). The reason is, the pixel sizes of such shape-showing type technology, is something like 1" pixels. So .... everything you typically search for (coins, rings, pulltabs, nails, foil wads, etc...) would be: a 1" pixel! doh. Even something you might THINK would be useful in showing shape (a horseshoe for instance), is nothing but a messy blotch of pixels. Thus, no, it's not going to show the difference in shape of a dime, vs a ring, vs a pulltab, vs a foil wad, etc....
