So not that far from you. In all honestly, the lightest detector I have used with very good results in the wet, salt sand, believe or not, is my Gold Bug SE ( which is probably equivalent in performance to the GB Pro or G2). I does balance in the wet salt sand, and has better than average depth and can hit low conductive targets. The only thing it is not, is water proof. In my areas ( up and down the NJ coast), I use the ground grab method to get the unit balanced fairly well, and then use the manual process to get it right on. When balancing in auto/ground grab, it balances somewhat on the positive side, so I then go into manual to get it spot on. I posted a YouTube video last year when I was on vacation in Long Beach Island showing how it can hit a fine 18K band and discriminate out a small, rusty nail. Hit the ring at about 7 inches in the wet sand.
You have all metal ID too, and that mode also shows your Fe, ground phase and ground balance numbers too. Cool feature.
One thing to know, is that deep targets in this environment will not bang hard and have a faint 'tick' type sound ( at least on my SE 2.9 version which has VCO audio). The Id will be off too, but if you hunt with it at discriminate level 20-21, you will not pick up nails or small rusty iron.
It works better than the Coin Strike, even with the CS in salt mode. Super recovery and separation too with the 11 inch DD. Only bad thing is, if you are hunting in dry sand, a lot of bottle caps will sound good and ID in the quarter range.
I run my CZ's mostly on the beach, but always take the GB too as it's just a light weight, super fast recovery unit that if I get to a spot with a lot of iron nails/bits in it, I take that out and it can always sniff out a few goodies the CZ won't due to it's concentric coil and it liking iron a bit.
