I'm with you regarding diving for abalone in this century. The titanium iron was last used in the late 1960's back when most of us thought that abalone and giant black sea bass would be conspicuous components of the California free-diving scene forever. I wish we'd of known then what we know now..... Fast forward to today and I wonder if we aren't going to have the same wishes about Uma notada and Crotalus cerastes of the Imperial Dunes sometime in the future.Wow. Just wow! a titanium abalone iron - I'm impressed (not that I ever dive for abalone, but that's still impressive).
