Solo diving is realizing that there is NOBODY but you. Keeps you focussed and honest to yourself. -can't offload all the "if this should happen's" and "what if's" onto your dive buddy. If you can't handle all possible issues, don't go there...[/QUOTE
Really? In a public pool? I don't think it requires a solo cert, or a solo mindset, or even the capacity to handle all reasonable issues alone, to dive in a pool with two lifeguards and a wife who is a swimmer.
Solo DIVING is a different animal, and anybody who knows me knows I strongly prefer diving with a team, and discourage new divers from exploring solo just to get underwater. But in a monitored pool, this is not really solo diving, because most of the risks of a solo dive are not going to occur in the pool, and if there IS an unforeseen issue, the surface is 15 feet away at MOST, and there are two capable free divers watching the pool, according to the OP. I mean, I'm risk averse; I belong to an entire community of seriously risk averse divers who are often mocked for our conservativism. But even I see little wrong with a certified diver practicing open circuit skills in a monitored swimming pool. (Put the diver on a rebreather, and this changes.)
