PADI Nitrox Course or Enriched Air

Extend your bottom time


What is Nitrox?

Nitrox is a breathing mixture that is commonly used by divers to extend their bottom time underwater. It is an Oxygen enriched mixture containing more than the standard 21% O2 found in air. This creates a mixture with less Nitrogen and in turn increases the amount of no decompression time we have. If staying down longer and getting back in the water sounds appealing, then the Enriched Air Diver course is for you

Our Enriched Air Diver course is held in the evening and runs for approximately 3.5 hours. During this time we cover why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. Discuss managing oxygen exposure and how to use the tables. 

What benefits does Nitrox have?

A few of the many benefits of diving with Nitrox:

  • Extended Bottom Time

  • Shorter Surface Intervals

  • Increased Safety Factor

What will I learn?

  • You will learn the procedures to dive with Nitrox with up to 40% O2 safely.

  • You will learn about different equipment considerations.

  • You will learn about managing oxygen exposure, how to analyse the oxygen content in your cylinder, how to label your cylinder properly and much more.

Will I have to change my equipment?

Most equipment available these days is compatible with using up to 40% O2 without having to change or modify anything. The main concern is with the cylinder. Worst case scenario is that you may need to have your cylinder O2 cleaned which is generally a pretty simple procedure.
