How long do you think a 3l pony is going to last at 50m? Not very long.

For those sorts of depths, I think you need to be looking at twin 10s at
the least. The problem with 10s is that the tanks are a bit short, so you
might find 12s a better height for you. It also gives you a bit more gas
which is handy if you want to do two dives on the same set.

The air in the tank/tanks on your back is your planned air supply.
A pony is an emergency backup.

Which do you need (want)?

This is probably a troll.....

Asking this question indicates you need more training. Asking this question

I wonder if he's related to the "I missed a safety stop from a 40ft
dive so I did IWR, am I bent?" guy.

Twins, separated at birth, reunited with help from rec.scuba! Who'da thunk
it?

Gary,

There is no way I would dive much below 30m without a proper set of
doubles -- a twinset -- with an isoltation manifold and 2 first
stages. In my mind, that much water between me and the surface is an
overhead environment. Someone else said it before, "If you think you
need a pony, you really need a set of doubles. I have found that to be
good advice.

Best,

-bob

From the infamous Cobber:

"As the folks on this list know my rule of thumb is:

-If you are diving with a single and think you need a pony, what you really
need are doubles.

-And if you don't think you need doubles, then you don't need a pony.

IOW if you are doing diving where safety cannot be assured by rule of thirds
and a buddy then you need doubles.

When do you use a single? When you are diving profiles from which you can do
a controlled ascent to the surface and not get seriously bent.

When do you use doubles? When you are doing dives which require you to do
stops or you wind up in the chamber.

Needless to say that many disagree with me for various reasons, mostly
because it would be inconvenient to use doubles for some reason or other, or
a money thing.

And in recognition of this inane hard-headedness which is typical of scuba
divers in that some are going to use a stupid pony with their single come
hell or high water I will recommend to those that you set up your pony as a
stage bottle (DIR style) and clip it on like a stage.

Many moan and groan that this will cause the bottle to get in their way. But
when attached to your tank you really can't get at your pony and it is a
horrible snag/drag/balance hazard. You can either clip it to your shoulder
and hip Drings or clip the top of the pony to your hip Dring and it won't
get in the way and will follow you around like a puppy dog if it is a proper
30 or 40 cuft Aluminum tank and not a steel one."
