He dives for fossils and artifacts in the appalachicola river near panama city. He sez the viz is a consistant 2' with a good light and there is always current but he finds awesome stuff. He has found Mastodon tusks and teeth, bar and cannon shot, petrified wood and the common shark teeth mixed in with whale teeth, arrow heads, civil war artifacts and tons more stuff.
Here are a few pix he sent of some of his finds.
