How about if nitrox is not available.
There are still places in this part of the world where only AIR is available.
Well ****, I think I'm stuck.:blinking: (This was not directed at you Centrals .... )
No course goes out teaching "Your XYZ course was wrong, you're going to die and kill everyone in the water, so do it only this way!" I have a piece of plastic in my wallet that says I can safely dive to 40m, one that says to 30m and another that says to 18m. Which one is right?
In the GUE curriculum, we're taught the Air rules (Navy, DSAT/'PADI'), and how we get our 32% guidelines/rules and a few other things about how/where/why about decompression in general and specific to the types of diving were doing (recreational, no 'decompression' and ceilings). So, we can default back to our teaching in our Fundies course (or a previous, PADI, SDI, XYZ, ... teachings).
(With 32%, we get 20% more MDL than with 21%, so we can go back to the rule of thumb of 110 rather than 130 due the nitrogen content.)
Say you have a trimix card, but you can't get trimix for a dive. Do you still do A (any) dive? Or do you sit on shore, sulking that you can't get trimix, and are soooo depressed that you don't dive at all? Most divers I know, going on a trip, usually find out well in advance if they have, or can get the gas we would like for our dives, and/or plan around not having those gases.
I really don't know what some peoples beef is with GUE, and getting hung up on this stated 32% fact on a supposedly 'worthless' piece of plastic according to the rest of the world (because it doesn't say PADI AOW).
Hey Lynn, Tell Guy I'm hoping to get the new suit wet on Sunday.
