what you are diving with.

Learn how to enter the right nitrox mix into your dive computer and check your limits before the dive starts.

UNDERSTAND WHAT’S IN YOUR TANK

Nitrox is popular because it gives certified divers more flexibility, especially on repetitive dive days.
The important part is knowing how to use it properly.

Less Guessing, Better Planning

You learn how oxygen percentage, nitrogen loading and depth limits all connect, so your dive plan is based on real numbers rather than assumptions.

This makes Nitrox especially useful if you are planning several dives, joining a dive holiday or combining it with deeper specialty training.

A Practical Skill For Future Dives

You will know how to check the gas mix yourself, set your computer correctly and understand the limits before the dive begins.

The course is not about making diving complicated.
It is about making your planning clearer.
