Those things are commonly used from New York to Florida, I believe usually for big Tuna. I've seen them used, they look like a contraption waiting to tangle, but somehow they do get out, untangled and attrack the fish. Last year when I was laid up I kept reading about them, and looking at them online, and dreaming about how to use them here. The goofy dude Tred Barta uses them all the time. I've seen them on Ebay quite a bit and various tackle stores with an online store, mostly in the Carolinas and Florida. I think Sekiu is the place they would work the best. Be kinda fun to try. I'll try anything, well fishing related, at least once.
