Enriched Air Nitrox Course

More bottom time on the deep walls, without changing anything else about your day.

The specialty that makes the most difference on this island, where the best of the reef sits deep and no-decompression limits are what end your dive.

Meeting point
Theory and boat session from the marina in Cozumel

About this trip

Cozumel is deep wall diving, so nitrox buys you real minutes rather than a theoretical advantage. The course is theory, analysis practice and dives, and it fits inside a normal diving week.

We carry analysed nitrox tanks on the boat, so once you are certified you can add them to any two-tank day with us.

How the day runs

  1. 1

    Morning

    Theory and analysis

    What enriched air actually does to your no-decompression limits, oxygen exposure, and how to analyse a tank and log it properly. Then you do it yourself on our tanks.

    Dive it

    Set your computer to the right mix and dive the walls with the extra minutes you just bought yourself.
