Spare Air

[Tuytles]

Looking for any general opinions from divers with experience on the new Spare Air 6.0 cu. ft. Or Spare Air N for eanx.
Also wondering on the Spare eanx, it is filled from a cylinder...any info on the reliability of the concentration percentage of eanx when filled from a cylinder?
Thanks in advance.
Searched forum before posting but if I missed a thread, please let me know.

You are not going to be breathing it long enough to worry about the percentage of O2. Spare Air is to quickly get you out of a bad situation.

But not a real bad situation. The limited size gives limited solutions, not that I'm opposed to the use of a Spare Air, but one must understand its limitations and decide if it meets the parameters of the solution you will need.

Why Spare Air and not a proper pony bottle?

There was a thread not too long ago on the Spare Air version marketed for Nitrox. Some felt it was a marketing gimmick, if I recall. What @BRT said above was also discussed. I'll try to find that thread.

By the way, weren't you in my Fundies class with Doug Mudry in 2014?

All true. But the level of oxygen in the bottle will not have an affect on the outcome.

I wish people would do the calculations of what their ascent rate would be based upon an estimated elevated RMV from various depths.

But I've heard Nitrox will make you feel better afterwords.

If you were going to carry extra gasoline on a road trip, would you just bring a quart or would you like to have a few gallons? If you went shopping and wanted to bring along some extra money would you just bring an extra 2 dollars or would you like to have more like 10 or 20 dollars? The same is true for bringing along extra air if you are going to at all. If you are going to clip on a Spare Air, you might as well clip on a small pony (19 CF) and bring a quantity worth having.

Don't have to, I know it can be slower than with no air at all.
