Ok....so with that, do any of you excersise your octo, by using it say on a safety stop or any other time? I have on a few occasions breathed mine while on a safety stop (15 feet) or is this just another stupid question?
Not a stupid question at all. In cave diving we always do a pre-dive check in-water. One of them is breathing 3 times off both your regs. Another is an OOA drill. This is important because while practice with a 7-ft hose makes it easy, it only takes one small mistake at the surface in putting on your gear to prevent that hose from fully deploying. So, we're checking both our regs with more than 1 breath, checking for correct deployment of the longhose, and making sure we're still up to par on our OOA drills. It's a great way to stay in practice. When I did a training dive over the winter, a bunch of other divers joined us for tune-up. Guess who were the only ones that were actually able to deploy their long-hoses? This guy, a newb at the time and NOT liking 7ft of hose wrapped around me, and my mentor.
Out in the ocean, we do this on the hang-bar/granny line instead of at the surface. Much more comfortable!
Good question. It's good that you want to check your redundant regulator and is a good habit, but try and incorporate it into a pre-dive in-water check instead.
