I was there in June and dove with Pro Dive Mexico. Nitrox was free on every dive. https://www.prodivemex.com/?gclid=CI2llM6p6scCFdgXgQodP9sKqg

As long as we're digressing from the OP's original question, I'm chiming in. I love Mi Casa! I stayed there last winter and will be staying there again this year in a different room. When looking for a dive shop, check out their morning dive times if the free breakfast is important to you. Because I chose an earlier leaving dive shop, I was unable to take advantage of the free breakfast (started at 7:30 I think?) Do you know what room you're staying in? Enjoy!
I call it nitrox at air-fill prices... Not free.When those diver using air pay the same price as those divers using nitrox, I call that free. What do you call it?
I appears that the dive ops in Bonaire made the investment up front for membrane systems so it doesn't really cost them any more for EAN than air. I believe most EAN on Cozumel is still PP blended so it cost the producer more for O2 and labor.
Some of the southern resort op that pump their own gas may offer free EAN.
Of all the criterion that I would use to choose a dive op "free" nitrox would be at the absolute bottom of the list.
Is this the same size tank? I don't think you are comparing apples to oranges (in addition to all the other mixed fruit involved: gear valet, fast boat, etc)- so it isn't the same 2-tanker.
