Standard MOD

[gsk3]

Ok, so the MOD uniquely identifies things except for a few cases that aren't a problem in practice. Got it ;-)

Yup, on the dives where you need a 120 deco bottle you're not going to need a 120 stage.

Having dozens of gas mixes is a great way to split up courses and make more money. Beyond that, it just confuses things IMO. GUE standard gases work great for 90% of the worlds diving. If you have local conditions that dictate other gases, do like JJ said in his very first standard gas article and create gases for those conditions, just don't change things every dive.

18/45 = 190
21/35 = 150

21/35=190

EDIT

and 18/45 is not 190 when used as a deco gas (240?) and it's not (for me) a 190 MOD for a bottom stage either.

Second edit (sorry)

21/35 = 190 (deco gas) and/or 150-160 (bottom stage? or 190 bottom stage ? or is that 18/45 ?)

18/45 = 190 bottom stage ? (or 200 or 220?) OR 240 (deco gas)

Help ... my head is exploding

That is not given. Look at some of the caves the EKPP is diving for instance.

I can think of at least one cave in tallahassee where you'd use both. luckily my 32% etc. stages are marked 100

Close to 190

200 for sure. I admit I have used it to 220 even though thats a tad more narcotic than 100 feet...15/55 would have been better in those cases.

Might be now with all the new marking schemes
(used to be 30/30 depending on which memos from HQ you got and did not get)

i was a little loopy on that dive
