as TSandM stated, I could not imagine doing one in my OW class, and most of us ended up with decent buoyancy control.I'm glad so many instructors contributing to this thread are responding that SMB deployment is taught during their AOW classes. I did not learn, which I greatly regret: it's such an important skill to have. (Especially here on Oahu, where currents' Hawaiian names all seem to translate to "The Fastest Way to Tahiti".) I've seen enough You Tube videos and heard enough anecdotes to understand that SMB deployment takes some practice to master, and that the first few attempts can be extremely humbling. I am NOT looking forward to that!
I now always carry one on every boat dive, and while I havn't done any shore dives since getting one, dont think I'm taking it off for any here.
The first time I had to deploy one is in the Gulf on the MOF Dry Tortuga trip, live boat drift dives, we all had to have one, but only had to deploy it on the surface
(I did so at the 20 foot safety stop to make their job easier ... Capitains tip .. If it's your first time under water, do it at the END of your stop, just in case you have trouble and rise up .. um yeah :blush: )
