I use the Sea Hunter II on South Florida beaches and if you like digging Bobby pins and nails like I did yesterday - along with treasure - it's for you. Whereas, the Infinium is a two-tone machine giving you some discrimination abilities - along with ground balance function. The Infinium will save you some worthless target digging but it's not a panacea - I.e., not a perfect solution. Match the tool to the task. On the beach, or even elsewhere? Want a factory warranty? Then get a Minelab Equinox. Or even a new, from dealer, White's TDI Beach Hunter. They have a one year warranty on them from now wholly-owned-by, Garrett. Or, even locate a Minelab Sovereign GT, but they're difficult to find, and you may have better luck mining for diamonds in your bathtub than finding the GT. LOL. I know, I tried.
