If you need a redundant gas source for your planned dives, why not learn to dive back mounted doubles? However, single tank dives can be planned with a minimum gas requirement to get you and your buddy to the surface safely in the event of an emergency. As always, plan your dive and dive your plan. Cheers.
Wow, you must be hilarious at parties. You realize a lot of dives are done on the fly. I know where I am going, but not necessarily what I am going to do when I get there. The “learn to dive doubles” argument makes no sense for 90% of divers. Not every diver is interested in wearing doubles and might not expect to be within arms reach of their buddy at all times. The idea of a pony is not about having enough air but having redundancy in the event of a catastrophic failure. I would never dive if I was going to plan every dive like it was the Andrea Doria. If you enjoy the complexities of being a tech diver and like to calculate and plan every dive, god bless, but there is plenty to see on a single tank.Accidents and buddy loss do happen, but your story does prove my point. Suppose one plans their dive to include a minimum gas calculation, SCR, and waypoints of the dive to check those things. In that case, one significantly mitigates the dive's risk and does not need to lug around a dead raccoon (pony bottle) with them unless required for decompression. Moreover, if additional gas is needed to conduct the dive, one should learn how to dive in a doubles configuration adequately.
Thankyou, thankyou, thankyou. I have been tempted to join in but reluctant as I get a little agitated when I get into a discussion of pony bottles with a GUE diver. I am sure that either GI3 or JJ must have been frightened by a pony when they were children.Wow, you must be hilarious at parties. You realize a lot of dives are done on the fly.

LOL! Best. Line. Of. The. Week.I am sure that either GI3 or JJ must have been frightened by a pony when they were children.

This is a newbie forum, those considering diving shouldn’t be expected to go tech before AOW.I am sure that either GI3 or JJ must have been frightened by a pony when they were children.

I am so stealing this line. It may take a years to find the right moment to use it, but I a. Stealing it.
Well, this is the forum for new divers, and for those who are not even certified yet. Many things you've learned are just not yet applicable. I suggest that doubles are among them.Folks can dive however they want; I don't care—but when there is a better solution to a common problem, I'll share what I have learned that might help in a forum such as this.
Doubles are much easier to carry? I dive steel 120s just so I DON’T need doubles.I am a hoot at parties, sir, lol. Nevertheless, you proved my point(s) with this statement: "The idea of a pony is not about having enough air but having redundancy in the event of a catastrophic failure."
1. Doubles are much easier to carry and create a balanced rig for weighting. (Considering most divers are over/underweighted anyways, imagine now adding an AL40 to that configuration on one side, oof.)
2. If a recreational diver knows how to calculate their minimum gas correctly, they would know how much gas they would need in a case of an emergency to get them or both them and their buddy to the surface. E,g a single AL80's minimum gas to 80ft would be ~ 1000psi with a ~ distressed SCR. So, to be safe, the buddy team would call the dive when one of them reached 1000psi in their tank as a level of conservatism, risk mitigation, and psychological safety
* "~" = according to the hypothetical diver team's surface consumption rate E.g. 0.75, 0.80. 1.0 cuft per minute.
