I have been using my newly upgraded V3i at a local freshwater beach. It is pretty worked over to the point that there is little left but pull tabs and bottle caps. So I am practicing on the tabs and gradually learning their signature on the search and pinpoint screens. Still not too sure about bottle caps.

So before my newly found confidence goes too far I would like to know how many of you have had a positive hit on a tab, with no other indication, and it turned out to be something good?
