I have a couple of rusty ones, and one that has never been near water.
From what I can remember catching with this lure - tailor, kingfish, salmon, trevally, bonito, Watson's bonito, frigates, small mack tuna, a small unidentified tuna, pike, snook, flathead, jewfish, trout, a couple of little reddies, a small whiting, squid, octopus, cuttlefish, a numb ray (a bit hard to remove the lure as the bastard kept giving me an electric shock, but it wasn't keeping my lure) and a blue swimmer crab (grabbed the lure in a nipper and would not let go until it hit the bottom of the boat) plus some other fish were unstoppable.
