Looks like fun. One of those things I just didn't get around to, although I've often thought about it. My brother dove, started when he was a kid. He got his first tank, and paid for it by recovering and selling jade at a place called "Jade Cove," on the California coast. When I was a kid it was called "Willow Creek," but then the new comers came along and renamed it for something the old timers already knew was there. I've been told the jade is pretty well picked over now, and hard to find. A friend of my dad found a large ledge of jade up stream, and tried blasting it, probably before WWII, because I was there right after the war and saw the ledge. The blast fractured the jade so badly that there isn't a 1/4 inch that isn't milky. Totally ruined the entire thing. Anyhow, great video, looks like a lot of fun.
