[QUOTE="Goldpick, post: 100028, member: 1695"] A lot of junk targets like foil and bits of aluminium will jump all over the place, especially at depth, both due to composition and irregular shape of the object. Coins VDI's should be more steady and repeatable, but may wander up or down by a couple of digits, depending how it sits in the ground, the depth, and whether it is located close to a junk target. VDI's will only be accurate or effective to a certain depth, beyond that, the detector is just guessing, hence why some people like to use larger coils to increase the effective depth of the detector. It doesn't hurt to dig some junk, as it will give you a better idea of what to look out for, or listen for next time, all a part of the learning process. :) [/QUOTE]
