Back mount pony bottle

Someone might not need double for a variety of reason and prefer a pony bottle. I use a 30 CF tank that i put on my left side. It does the job and it s an independent air source. Totally safe also. All depend of the diving you intend to do.

Pony’s have their place as do bailouts ( larger pony’s) if you are an instructor and not offering a variety of options to the divers you work with I would suggest more contemplative thinking

generally with more contemplative thinking the diver will determine that a pony bottle is not necessary, and if it is, then they go to a true redundant system.

What is truly redundant with manifolded doubles which have the possibility of isolation valve failure. I know it is very rare but if it is a possibility then manifolded doubles are not as fully redundant as a pony and are a lot harder on the back.

Redundant like these fellas? I dove a 133 with my pony and we all surfaced within 1 minute of eachother. Cold was the limiting factor after 80 minutes in 47/48° and not finding.
