PADI Enriched Air Diver Speciality COURSE

PADI PADI Enriched Air Diver

The PADI Enriched Air Diver course is PADI’s most popular speciality scuba course. Why? Because scuba diving with enriched air nitrox gives you longer no stop dive times, especially on repetitive scuba dives. If staying down longer and getting back in the water sooner sounds appealing, then don’t hesitate to become an enriched air diver.

Who should take this course?

The Enriched Air Diver course is perfect for anyone who has earned their Open Water Diver rating (or higher), and wishes to enjoy extended dives. We also offer the Enriched Air Diver course alongside the Open Water Diver course, so those learning to dive with us can begin their diving journey using nitrox right from the start.


“Absolutely chuffed with how this weekend has gone, I’m filled with absolute gratitude towards you and Robin for sharing your knowledge with me and giving me such first-class tuition. Thank you so much!” 


Open Water & Dry Suit Diver Student


The Enriched Air Diver course can be taken as a theory only course, as all the knowledge development and practical skills take place before your dive begins! We also offer the option to add two enriched air experience dives to your course for those who would like to have their first enriched air dives alongside their dive instructor.

During the theory session you learn why diving with gas that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During the practical gas analysis and dive planning workshop sessions you will learn to manage oxygen exposure and plan enriched air dives with your personal dive computer. You will also practice analysing the oxygen content in your cylinder, and use effective cylinder markings to record your analysis.


Most modern scuba equipment and dive computers can be used with enriched air, but we can discuss with you if your gear meets manufacturer recommendations. Scuba cylinders must meet oxygen service standards, and these are available to use on the course if you don’t have your own. We have multiple oxygen analysers to use, so you will get experience with different models, preparing you for a variety of analysers you may come across at a dive centre or resort in the future.

Hidden Depths Scuba School run two weekly pool dives around Bristol, primarily for scuba training, but also open to club members
