it might not be very likely but i was just using it as an example
that is the main purpose of the pony(redundant air source)
but it could be handed off easyly IF necessary
thanx all seems like im actually going to bungee the hose and the reg to the pony afterall so that i can either grab the reg or hand it off.
i am also planning on rigging a handle onto the bottle similar to the slung setup so that its not dropped as easily
As has been pointed out very well in this thread, you're trying to solve problems with complicated solutions when simple solutions exist. What will happen is the panicked OOG diver will grab your primary out of your mouth while you are fiddling around trying to get your pony off of your main cylinder and you will have to go to your air2 anyway. Throw in a dislodged mask and things get a bit more difficult.
A pony is there for catastrophic loss of your gas. It is not for donating. The reason you have a 5' (or 7') hose is to make donating the primary easier and give some space between you and the OOG diver until things calm down and you and buddy can make a contolled ascent.
