Been water hunting with my Equinox. Got 4 gold total with it. But what is interesting is i tested something and hope you don't find the same thing. Running all metal on the deep deep stuff. I hit a lot of solid - iron hits with one shallow arrow showing. Dig down real deep and quite a few were either sinkers or pulltabs Needless to say i dig it all in the water now. Did get a nice 14k mens wedding band that stayed a solid 16 four scoops down. So not sure if gold will remain more stable? I'll still keep using the Equinox but its no CTX on id'ing anything. In fact it's a pain in the butt! You get to submerge yours test all metal and dig the deep deep iron stuff and see what happens. And yes in the water 1 arrow can be over a foot deep!
