Do you want to extend your in-water dive time? Do you want to gain a better understanding of decompression and use a gas that will allow you to do that?

The answers to these two simple questions are the reason why nitrox is the most popular diver specialty in the industry. Nitrox has proved to be so popular within the diving community that many dive centers offer only nitrox as their breathing gas.

Nitrox use has many benefits for sport divers. But most divers use nitrox because it helps better manage the risk of decompression sickness. In the Nitrox course, you will learn the pros and cons of using nitrox as a breathing gas for sport diving. 

You will learn new skills and extend your diving knowledge, including information such as why nitrox is often a better choice than air. Most importantly, this course will teach you how to plan nitrox dives, what you have to do to stay safe when you use nitrox, and how to analyze and label dive cylinders so that there is never a mix-up.

The Nitrox course may be completed using RAID’s REMOTe-Training curriculum option. This is significant because it means you can earn the Nitrox certification by attending virtual classroom sessions on your computer. You will complete the online course academics; your RAID Instructor will take time to review your results and then demonstrate how to use a nitrox analyzer safely.

If you do not have access to your own analyzer, you can download the Nitrox Virtual Analyzer app, powered by RAID, from your favorite app store.

Download the app from the Google Play Store.

Download the app from the Apple App Store.


During the Nitrox program, you will complete the online academics and learn the following:

  • How to use nitrox mixes from 22%-40% oxygen 
  • How to plan dives to a planned maximum PO2 of 1.4 bar and a contingency PO2 of 1.6 bar
  • What the causes and effects of oxygen toxicity are and how to avoid them
  • How to safely analyze the oxygen content in a nitrox mix and know the depths at which you can use it
  • How to label your nitrox cylinder appropriately
  • How to fill in a nitrox log
  • What the benefits of enriched oxygen are for sport divers

Note: Two open water dives may be offered by your instructor for this program, but these dives are not mandatory.


  • You must be a certified RAID Open Water 20 diver or equivalent. 
  • You must be a minimum of 12 years old.
