whats the main difference between a small tank with a alternate reg on it and a spare air?
One is a useful piece of dive gear, and the other is a Spare Air.

whats the main difference between a small tank with a alternate reg on it and a spare air?
(i dive a hp40-the same size as an al 19)
Don't mean to hijack this thread, but since I am interested in buying a pony myself and I saw the above quote I am curious as to what an "hp40" is.
Thanks!
Me, too - but I couldn't find one on the net.I read it as a High pressure 40 Cubic Foot

I can see going with larger staging bottles, but for bail out bottles, 40 cf sounds like over kill. Ok if it's the same weight as a 19 cf and same price, but I doubt it.

But get this!! At no extra charge one can have a 1.7 CF Spare Air that weighs 1.2 pounds less. Is that going to give a full breath at 130 ft?
you just convienently reach for your pony reg(i dive a hp40-the same size as an al 19)
Uh, yeah - some do. Not many, I don't think - but I've seen some. Their reasons don't wash well, tho.I don't think (hope?) that anyone would consider diving a Spare Air to 130 fsw as a redundant source but what if you are planning on flying to the Keys to tool around a 30 ft. reef using rental tanks. For one you could travel with the Spare Air and secondly it is much easier and more comfortable to take on those shallow dives - and a lot better than having nothing.
