The PADI Enriched Air Diver Specialty course, often referred to as the Nitrox course, is designed for divers seeking to extend their bottom times and reduce nitrogen absorption by using enriched air nitrox. This course provides the knowledge and skills necessary to safely plan and conduct dives using enriched air with oxygen levels between 22% and 40%. It's an ideal course for those looking to maximize their dive time, especially when completing multiple dives per day.


Course Objectives and Structure

The course aims to educate divers on the benefits, safety considerations, and procedures for diving with enriched air nitrox. Through a combination of theory and practical application, participants will become proficient in the use of enriched air nitrox for recreational diving.


Knowledge Development

The course begins with a comprehensive knowledge development session, delivered through PADI's eLearning platform. This self-study component covers:

  • The advantages and disadvantages of using enriched air nitrox.
  • How to manage oxygen exposure and analyze the oxygen content in your scuba tank.
  • Setting your dive computer for diving with enriched air nitrox.


This foundational knowledge prepares divers for the practical aspects of nitrox diving and ensures they understand the importance of oxygen exposure management.


Practical Application

While there are no mandatory open water dives for this course, divers are encouraged to apply their newly acquired knowledge in the water. The practical application can include:

  • Analyzing the oxygen content of your scuba tank and labeling it appropriately.
  • Planning nitrox dives using dive tables or dive computers.
  • Discussing real-life scenarios and problem-solving with your instructor.



Upon completing the knowledge development and practical application components, participants will earn the PADI Enriched Air Diver Specialty certification. This certification opens up new opportunities for longer dives and shorter surface intervals, enhancing your overall diving experience.
