Snowbear:Hehe... almost all of those 21 reasons are easily preventable, negating the need for that "one more breath of air... just one." In the event of an O-ring failure, you can still get that "one more breath of air" from the tank as you are ascending. Anything for a buck I guess
Depends how long it takes you to react. Have you ever had a 1st stage o-ring blowout? When it happened to me at 25m+ all I could think of was "where the heck is that noise coming from?" The noise was overwhelming. I never even thought about looking at my SPG, I was just spinning looking for the source of the noise. Only when I rolled on my back to look up and found myself in a cloud of bubbles did I realise what was going on, by which time most of my air was gone.
But my buddy was there for me so I didn't need a Spare Air.
