And dives with three second stages while doing classes. The Air2, Duo aire and the like have a lot more air available to them via their hoses. They will inflate a BC VERY quickly. He likes that feature, while I do not. I like my power inflator to put it in slowly... I can regulate it better that way! However, when he is not instructing students, he takes the normal octo off. Less clutter during a dive.
