Ok, how about we discuss what kind of Estes model rocket parachute to use?
Its designed to fit the purpose; its just not big enough. Just like a Scarce, I mean Spare Air.

RIX SA-6B....
I refuse to carry a towel with me on an airplane...
Who knows what acts of irresponsibility it might lead to!
Obviously not a Hitchhiker's Guide to the Galaxy fan...
ALWAYS bring your towel.

True... I hadn't even heard of it until a month or so ago on this board... had to do a web search on the significance of 42 & towel to find out what was going on.Originally posted by roakey

I guess I will have to read the book(s) when I learn how to read.
ok...saying that you'll jump out of an airplane with a towel only is like saying that you'll descend to 130 ft with a Spare Air only.
but anyway, i think we're getting into an argument about semantics and not diving. how about we just get your opinion of what you would do if you had to ascend from 130 ft with only a Spare Air. just hypothetically speaking of course.

-ascend as much as possible before taking my first breath.
-take as small breaths as possible.
-for every breath I got out of the spare air, I would try to get one out of my back tank as well while ascending.
-hang at 15ft until all usable gas from all sources is gone and then rise as slowly as my one last breath will allow me to.
-break the surface and gasp like hell
-have best friend deck me hard for being stupid.
And flying into the ring with a chair and a towel

Theoretically you should be able to do a controlled ascent at 60 ft/min from 130 with a spare air. But for a typical diver that runs out of air at 130 it would be a reasonable assumption that his/her breathing rate would jump up to 1 cuft/min at least. At 130 feet this would be the equivalent of 5 cuft per min, So the spare air should be good for about 4 or 5 breaths and then a taste. Not much of a security towel, err blanket, is it?
The only use I could envision for the things are as a drysuit inflation source if you could find a suitable valve, and even then there are much cheaper (and better) alternatives.

Nope... we are not talking about descending with the Spare Air... we are talking about trying to ascend with it... stay on topic.
Nope... I refuse to lend my good name to such folly.
But this does bring into focus and interesting question:
Why are you working so hard to justify the Spare Air? Grasping a straws and all.... hmmmm....

Since......
"This is NOT intended to start another discussion along those lines..."
..and the question is....
"Any thought on what the best way of using the 3 cuft would be?"
I vote that you begin your ascent, stick the thing in your mouth, suck on it until it is empty and hope for the best. The other options, take a breath, wait, take a breath, etc. make it too easy to hold you breath resulting in injury. If ya got it, use it. (K.I.S.S.)
Anyone ever take one down and play with it to get some first hand experience?

How about it Uncle Pug? Do you have some first hand info?
Yep....
Goes back to when they first came out...
Buddy had one... wouldn't dive without it...
I bought one so I could feel secure too...
Played with it... seemed ok...
Bought one as a gift for another buddy who had a bad OOA habit...
Things went along fine... I never needed it....
Then one day while spankin' fish on a local 60 fsw reef I did something stupid....
SOB buddy had already run OOA and gone up...
I went after one more fish and ran my air down to ~300 psi....
But I had the Spare Air so no worries....
Then I had to unhook the anchor and hump 30 feet of 3/8" chain up over the reef before coming up....
But I had the Spare Air so no worries....
I didn't notice it was getting harder to breath because it is always harder to breath when you are dragging that much chain around boulders....
And then I was OOA...
I sucked one last 1/2 breath and pulled a vacuum on the AL80...
And found my Spare Air and flipped the little lever to turn it on...
In those days you had to turn them on... sort of a failsafe to keep the air from leaking out....
Then I took my useless second stage out of my mouth and plugged an equally useless Spare Air in...
It was totally flat... I have no idea how that had happened.... it had checked out good to go before the dive....
And I no longer had the 1/2 breath...
Well didn't do safety stops in those days anyway....
Obviously I made it...
But have you ever pretended to breath without moving any air by heaving your chest...
Try it sometime... let all the air out of your lungs and see how long you can go without inhaling... it isn't fun but heaving can extend your ability to keep from inhaling a few more seconds...
I'm glad we weren't at 130 fsw....
I figured I didn't need to take the Spare Air diving anymore....
I needed something else.... it took awhile and a few mistakes but I finally found it.
