Smarter gasfor steadier dives

Understand how enriched air nitrox works, how to plan with it, and how to use it safely to extend your time within no-decompression limits on the dives that matter most.

Nitrox

A practical planning tool, not a mystery setting.

This course teaches you how to use enriched air nitrox as a practical tool, not a mystery setting on a cylinder.

You'll learn what changes, and what doesn't, when you increase oxygen content, how to analyze and label cylinders correctly, and how to plan dives within appropriate depth and exposure limits.

The focus stays on safe habits and clear thinking: understanding your mix, your limits, and your margin. With those pieces in place, nitrox becomes a straightforward way to add more useful bottom time to suitable dives.
