After watching the T.V. show, "The Bearing Sea Gold", do these sea miners have claims out in the ocean or is it a free for all? I saw some pretty cheesey boats set up to sluice the ocean. Most of these pontoon boats looked really busy with stuff every where. I also see they seem to dredge about a 3 wood away from shore. Is it that easy? Can you stake a claim in the ocean floor?
