Enriched Air Specialty

Enriched Air, also known as “nitrox”, is a form of breathing gas that allows divers to extend bottom time and reduce nitrogen loading. It is PADI’s most popular specialty course. Plus, this course also counts towards your Master Scuba Diver rating..


You will learn essential safety concepts and enriched air dive planning and preparation through videos, audio, graphics and reading. Progress through the material at your own pace using a desktop, laptop or mobile device. You’ll complete knowledge reviews and exam online.

Once you have completed the online portion of the program, your instructor will answer any questions you may have and guide you through the practical application portion of the course—at a minimum, you’ll apply what you’ve learned by analysing gas and marking and logging cylinder contents.
