> I have some questions about your back mounting:
Ok Jim, let me see if I can help you.
> -How do you check the pressure of your pony while underwater?
With a pressure guage.
> -If you use a gauge, how do you have the gauge rigged?
With a standard length hose that is attached on the right side
of my harness.
> -How do you keep the bottle and hoses from snagging fishing line, reel
> line, nets, etc.?
I have never had it snag on any of the above, and doubt that it
would be any more likely to snag than my main tank. If the pony
were to get snagged on any thing, I would deal with it in the
same way as if my main tank had been snagged, cut whatever I was
snagged in.
> -Can you quickly and easily pull it off when you have to while underwater?
You don't. There is no reason to.
> -Can you quickly and easily put it back on while underwater?
See above.
> -How do you check for leaks during the dive?
Check your pressure guage every few minutes. If the pressure is
dropping you have a leak and it's time to end the dive. If my
main tank regulator were to develop a leak I would also end the
dive..........wouldn't you?
> -If you do the above, how many times during the dive do you check?
About once every 5 minutes.
> -Can you reach the valve?
There is no need to reach the valve. If you develop a leak it is
time to end the dive and there is no need to shut down the
regulator as it in no way will it effect your main tank air
supply.
> -Isn't this weight on the side of your tank just one more thing to fall
> off or snag?
Personally I don't use a weight. The balance isn't a problem
for me. If you can't securely attach the weight, then I dought
that you can mount your tank to your BC. If your afraid of
getting snagged, go back to the swimming pool where it's safe.
Sooner or later you will get snagged on something, and you just
have to be prepared to deal with it.
> -How does this weight account for hydrodynamic drag unbalance?
The weight is to counter the buoyancy difference. As for drag
unbalance, there is more drag effect from my camera gear, or
bug bag, or spear gun, or whatever else I am taking on the
dive with me.
> -What do you say to the diver next to you in the tank rack when you bash
> your pony into his gear?
I am careful, and thus don't have that problem. By the way,
last time I checked, my single with a pony wasn't as wide as
your doubles.

> your doubles.
Funny, I don't remember suggesting a back mounted pony with
doubles.
> Note that none of these questions have to asked for a stage rigged bottle.
That's true.
