Went diving this week off Pompano Beach, Fl. Wreck in about 120 feet. Very cool diving. Water at 86F. Dove with absolute morons with whom I was buddied up with on the boat.. $10K of diving gear. 120Lb steel tanks with 30lb ponies. About 50 other pieces of sundry gear. Almost every piece of superfluous gear known to man. Spoke the greatest game you ever heard. Strutting around the boat discussing their previous exploits. One of them asks me if I would buddy up. Reluctantly I agree. No-one else available. Then when underwater -- they are completely freaking useless. Waving around like drunken seals. Hands all over the place. No bouyancy control. Blew their tanks in about 15 minutes. Up they go. I wave goodbye. I stuck around on the wreck with another group for another 20. Get back on the boat and these monkeys are puffing away on cigarettes talking about their incredible dive. I go down with them on the second dive with 36% nitrox. Supposed to be a reef at 60 max. I warn them that I'm on nitrox. They're on air. We enter the water together. Immediately they go onto the back of the reef -- and dissappear off to 120 feet looking for "bugs". Their SMB has insufficienct bouyancy (they refuse to use the one given to them by the captain), and the one moron spends the entire dive dragging the useless thing behind him at 60 feet. They blow their tanks again in 15 minutes and I take the SMB and finish the dive with another group. Get back on about 30 mins later and they say: "You're lucky YOU have nitrox, that helped you stay down longer, we're taking nitrox next time so we can stay down longer". I say, give them nitrox next time and let Darwin take care of the details.
