...but just in case he is not, the situation he describes is highly plausible. I have seen it once or twice myself. Just because someone goes out and buys all the gear doesn't mean they are squared away in its use...maybe they were new to that gear config or maybe they just bought all that crap because someone on the Internet told them to. Regardless, without practice and possibly some training, a DIR/Hogarthian rig can make someone look like a total CF if they use it improperly.Lawman once bubbled...
They had enough tanks, hoses, canisters, lights, snaps, manifolds, and assorted crap that they could hardly move. They looked like they'd escaped from an ICU. They had to be helped into the water and it took two guys to get them back on the boat and untangled. That 7' noose...er, hose caught on everything.
Any more stuff and we'll have to put them in the water like a burial at sea. Slide them off a board.
