Best Size Pony Tank?

[TRACI]

I really like the idea of having a pony tank instead of spare air, What is the best size pony tank for recreational warm water diving? I generally never dive over 100 ft, I am still relativly a new diver.

this will open all kinds of answers which all will feel is the right answer. me personally, i use a 30cf pony which i sling on my right side.

Spare Air or Pony?

Thanks for the info, attaching to my tank or sling was going to be my next question. Too many decisions!

You can go as small as 19cf, but I think 30 is probably the sweet spot. If you think you may ever go down the technical route, save some money just buy a 40cf tank.

In either case, slinging it to the left if probably one of the better carrying options.

Of course, most of these points were covered in the thread linked above, so this is redundant if you read that already...

In order to correctly answer your question, you need to know what you SAC rate is. That number is used to compute gas needs to SAFELY ascend from depth. Without it, it's nothing but a guess as to what you need.

As stated previously a 19 or 30 is best for most recreational dives.Stay away from the Spare Air.

I have a 30cf pony-19 did not have enough air and the 40 was physically bigger than I wanted to go...although it would have worked OK.

I agree with a 30cf, not how you carry it is personal preference...I have mine mounted on my tank.....

from 19 to 40 cuft as many folks pointed out. depends on your diving environment, skills, equipment.
