Although failures like this are extremely rare, this gives me another reason why I like to carry a pony bottle for both solo dives and buddy dives.
I liked your advice so much I decided to buy a pony a couple of days. I dive twice a day every day that I can and having a redundant air supply seems like an OK idea to me. I just got it set up today and am pretty stoked
Thanks to all with helpful input. I really appreciate it.
