Actually, HOG is not a type of diver, rather a gear configuration.Otter:Do HOGs use H-Valves to provide a redundant 1st stage?
Quarrior:I have found neither recommends the idea of the "H" valve over the use of a sling/stage bottle as a true redundant air source.

Now with that said, I have been wondering the same thing. In checking with my instructor and my mentor I have found neither recommends the idea of the "H" valve over the use of a sling/stage bottle as a true redundant air source.
Right now I'm working on getting a 40cuft AL to sling up for my dives below 65ft or in cold water like is the norm for me at that depth and will be for all depths this winter.
Not trying to start something here, but, wouldn't having to switch to the second reg on an H/Y valve constitute an emergency assuming the primary failed for some reason? Thus the independent air source would be justified?MechDiver:The two do not serve the same purpose. Difficult to explain and I don't have much time, but two regs on an H or Y valve provide redundant regs, nothing more. However, two regs on an isolated manifold with doubles provides equipment redunduncy as well as redundant air.
A slung pony serves as emergency air only (or should).
