Pony Bottles

Just for the record I agree with SCUBAMedic on the use of a pony. Scottk where did you come from? Sounds like you need a
bottle of spare air 2.3 cu. ft. size to go with that bottle of Jim Bean.

I hail from a galaxy far away, a long time ago...

I am still tinkering with the position of mine. I have done a couple of dives and it still seems a bit in the way. I have a modified Hogarthian harness and a 25cu ft tank.

Any tips on how it should hang or even a picture would be appreciated.

Cheers
Nick

"Stages should be aluminum 80's. These swing equally from negative to positive with air, less negative with gas, by the amount of the air or gas carried. They are rigged with stainless steel bolt snaps, the size of which is determined by whether or not your diving requires gloves, and those are attached by a piece of 1/4" line run under a hose clamp halfway down the tank and tied to the neck. The upper clip should be tight to the break of the neck, the lower clip should have plenty of tail to work with. The bottle needs to be held close in the front and lose in the back to prevent drag. There should NEVER be any metal to metal connections of any part of your rig."

Substitute AL40 for AL80 above

Here you will see a proper AL40:

Scott,
Your such the 'guru' of diving!

You know who this is...

Thanks Scott. That's how I have set it up. Maybe I'm expecting too much. It does seem to be a bit in the way and it doesn't really sit in the slipstream of anything.

Maybe I just need to do a few more dives with it to get used to it.

In addition to cylinder rigging there is also the issue of D-ring placement. I have my upper D-rings up on the harness in the vicinity of my collar bone. IMO if the D-ring is too low the cylinder is no longer in your slipstream and awkward.
