Best reply yet!

I stole the line from someone else, so I can't take complete credit for it, although the last part about "being closer to the surface the second time" was mine.

But how is he going to carry that on an airliner? I think the poor guy just wanted a fall back when he was away on vacation. Carrying anything larger than a 12 cf or maybe a 19 cf is problematic for airline travel. TSA stole the tweezers out of my checked luggage, a 40 cf bottle under his arm may not pack very well. N

The TSA actually allows empty cylinders with the valve removed in checked luggage. Just make sure there aren't any "Nitrox" or "Oxygen Enhanced" or "O2 Clean" stickers anywhere, or they'll all freak out even though it's empty.

It's right in their regs. They don't care what size it is, although with current weight restrictions, it eats up about 1/2 a bag's weight allowance.

AFAIK, they don't allow any tanks as carry-on.

I think the spare air debate is rather humorous, and I probably knew when I hi-jacked the thread it was just like hitting a hornets nest with a stick, but -
My concealed carry analogy was that the spare air gives you a possible redundant air system when you can't take a pony set-up. ie: My trip to Bonaire this spring. If I dive with respect to the equipment (spare air) limitations, no deco safety stops, just an emergency ascent, equipment failure situation, I think the spare air is a viable option.

Sorry, Thing sent before I was finished.
The spare air system is not ideal, and it would be foolish to dive deeper then the redundant air allows and then count on it to save you. But I think it is also a little strange to say that if I can't take a pony tank I'm not going to take anything. If you give someone the option of making an emergency ascent from 80' on 1 breath (or maybe no breath) or 10 or 20 or 30 breaths - I know what my answer is going to be. Give me even an extra breath or two and I'd be happy.
Makes sense to me.

Please don't take anything that's been said personally. Lot's of us here love to razz on the spare air, I know I do. :14:

Look at it this way, if you were diving with me... then I have your emergency gas supply, and 1/3 of my doubled 119's would give you about 79 cu.ft.. I like those odds a LOT better than a little spair air bottle.

 

[salth2owannabe]

No hurt feelings here for sure, I like these discussions. Watching football and talking diving while there is snow on the ground outside isn't a bad use of a couple of hours.
For sure 79 cu. ft. is better then 3. But if 3 gets me to you all that much better, I gues I'm just in favor of redundancy. (Practical redundancy based on availablity).
Do they have small pony set-ups at these dive resorts for rent or would they look at you cross eyed?

OP...please do a search. Spare Air is not a good choice in a redundant gas delivery system.

I agree completely...

I just got two nitrox ready spare air's for xmas this year and only paid about $300 and I got the really big ones too! Mine are 80 cu ft each, but I had to provide my own regulators and rigging.

Has anyone here actually tried to carry a 40 to 80 cf cylinder on an airliner to a foreign destination and back? You may be able to check it but do you think an aluminum 40 would fit in a suitcase? If the cylinder is in your suitcase where will be your cloths and the rest of your junk? There are LIMITS on how much you can carry. N
