Calling out the Nitrox Posers!

Better idea!! Fill empty whiskey bottle with tea. Take INTO the water with you!

Not true, nitrox tanks only have to be O2 cleaned if they are seeing O2% higher than 40% (i.e. partial pressure blending).

Many places blend partial pressure for sub-advanced Nitrox mixes...

I think GUE recommends EAN32x for all open water diving up to 90FW.

Per GUE, air is the appropriate gas for filling tires.

I think what you mean to say is many places bank 40% or lower nitrox and then air top to lower the O2 content to the desired mix. This type of filling, as I indicated above, does not require O2 clean tanks since the tank is never exposed to 100% O2.

Compressed gas in a cylinder tells me "analyze before use."

Well, Cozumel Blue XT Sea...yes, I did bring my analyzer and check my air tanks.

You were filling tires while in Cozumel?

Heh. I was doing shallow, warm water, single al80 dives. I know where air has a use and where it doesn't. You will notice that my certifications are from NAUI Tech, not GUE

I don't know if I was correct in saying "many."

However, I know of at least one shop (and one boat) that only blends partial pressure. Air on top of oxygen.

Then those tanks would have to be O2 cleaned, because they would see 100% O2 content.
