Per the SDI manual, The Solo Diver, used for the Solo Diver course, see paragraph 3 below:
I am not going to carry a spare mask and a spare kitchen sink for a simple solo dive. If I have a mask problem and it somehow is teleported into an alternate universe I will just execute a simple return to surface. I have completed entire dive sans mask and that was part of my course, swimming without a mask so those who are solo certified, at least through SDI, should have completed a no mask exercise. It was also a part of my YMCA and NAUI scuba diver and advanced courses in 1966 and 1976.
Nope. You summed it up.So, is there any appreciable disadvantage to leaving the Air2 on my BCD that I'm not seeing?
DIsclaimer: I'm pretty new to diving and am working through the process of thinking about redundancy/safety in solo or self-reliant situations. So, please be kind.
The reg setup I'm starting with has an Air2, and I'm adding a 19cf pony with it's own primary/octo.
I'm not sure I see where the SDI manual is coming from with respect to a pony and an Air2 causing issues that wouldn't be there without it. With an Air2 vs not: In both cases, you still have an inflator hose with connection, the two air management valves. and the LP hose. So, the only added piece of kit is the actual regulator. That gives one additional failure point and negligable additional drag. It also does give some marginal additional backup of a second AAS. If, by some remote chance, the Air2 reg suddenly fails and starts free flowing, you can simply diconnect the LP hose and plan on a manual inflate when the time comes. Any other failure mode would be present with a normal BC inflation system as well, no?

My bad on the terminology fail. My pony has just a first stage and a single, emergency-use-only, regulator. I definitely mis-used the terms primary/octo there. I definitely *don't* need two regs on my main tank and two on my pony!I personally see no point in an "octopus" in addition to a second regulator on the redunant tank.
