Discover the benefits of diving with enriched air Nitrox and learn how to make the most of your underwater adventures.
The PADI Enriched Air Diver course is one of the most popular scuba diving specialties, helping qualified divers understand how Nitrox can extend their no-decompression limits and reduce nitrogen exposure.
With friendly, instructor-led training and practical experience analysing Nitrox cylinders, you'll develop the knowledge needed to plan and enjoy enriched air dives safely.
Best of all, no diving is required to complete your certification, making this an ideal course for the winter months.
Course Price includes PADI eLearning, practical training and certification.

PADI Enriched Air Diver – Discover the Benefits of Nitrox
If you've been diving for a while, you've probably heard other divers talking about Nitrox. Perhaps you've noticed Nitrox cylinders on a dive boat or seen enriched air offered on a liveaboard holiday.
But what exactly is Nitrox, and why do so many divers choose to use it?
Enriched air Nitrox is a breathing gas containing a higher percentage of oxygen and a lower percentage of nitrogen than normal air. By breathing less nitrogen during a dive, you can potentially extend your no-decompression limits, particularly on repetitive dives.
This can be especially useful when exploring reefs, enjoying multiple dives during a holiday or planning a diving itinerary where you want to make the most of your available bottom time.
However, Nitrox also introduces important considerations, including oxygen exposure limits and maximum operating depths. Understanding these is a fundamental part of the course.
At Sussex Diving, our PADI 5 Star Dive Centre in Selsey, West Sussex, we believe in helping divers understand not just how to use their equipment and breathing gases, but why the correct procedures matter.
Our friendly instructors will guide you through the theory and practical skills at a comfortable pace, giving you plenty of opportunities to ask questions.
What Will You Learn?
During your PADI Enriched Air Diver course, you'll learn:
- The benefits of enriched air Nitrox: Understand how reduced nitrogen exposure can influence your dive planning and no-decompression limits.
- Understanding oxygen exposure: Learn why oxygen concentration matters and how to remain within appropriate exposure limits.
- Maximum operating depth: Understand how the oxygen percentage of your breathing gas determines its maximum operating depth.
- Analysing Nitrox cylinders: Gain practical experience using an oxygen analyser to check the gas mixture in a diving cylinder.
- Cylinder identification and procedures: Learn how Nitrox cylinders are identified and the importance of confirming and recording the gas mixture before diving.
- Setting your dive computer: Understand how to configure your dive computer correctly for enriched air diving.
- Planning Nitrox dives: Learn to select suitable breathing gases and plan dives within appropriate depth and exposure limits.
How Does the Course Work?
The PADI Enriched Air Diver course combines convenient online learning with practical, instructor-led training.
Step 1 – Complete Your PADI eLearning
Start with your PADI Enriched Air Diver eLearning, which allows you to work through the theory at your own pace.
You'll explore the benefits of Nitrox, dive planning considerations, oxygen exposure and the procedures used when diving with enriched air.
Step 2 – Practical Training with Your Instructor
Once you've completed your eLearning, you'll attend a practical training session with one of our experienced PADI instructors.
We'll show you how to analyse a Nitrox cylinder, verify the oxygen percentage, understand cylinder identification procedures and configure your dive computer appropriately.
This is an opportunity to ask questions and become comfortable with the procedures you'll use whenever you dive with enriched air.
Step 3 – Earn Your PADI Enriched Air Diver Certification
Once you've successfully completed the required knowledge development and practical assessments, you'll earn your internationally recognised PADI Enriched Air Diver certification.
No open-water dives are required to qualify.
An Ideal Winter Scuba Diving Course
Not everyone wants to spend the colder months diving in British waters, but that doesn't mean your scuba diving education has to stop.
The PADI Enriched Air Diver course is particularly well suited to winter training because you can complete the entire certification without entering the water.
It's also an excellent way to prepare for a forthcoming diving holiday, Red Sea liveaboard or a return to regular diving when the weather improves.

Optional Practical Diving Experience
Learning how Nitrox works is one thing. Putting that knowledge into practice on a real dive is another.
Although no diving is required to complete your PADI Enriched Air Diver certification, we offer an optional practical diving package for those who would like to experience using Nitrox underwater.
Join our friendly instructors for two Nitrox training dives, where you'll have the opportunity to apply what you've learned during your course.
You'll practise preparing for Nitrox dives, checking your breathing gas, configuring your dive computer and planning your dives using enriched air.
It's a great opportunity to build familiarity with Nitrox diving procedures before using enriched air independently on future diving adventures.
Your Optional Diving Package Includes
- Two instructor-led Nitrox dives: Put your training into practice with guidance from our experienced instructors.
- Two Nitrox cylinder fills: Your enriched air fills are included.
- Scuba equipment rental: The diving equipment needed for your training dives is provided.
The practical diving package can be booked alongside your PADI Enriched Air Diver course or separately at a later date.
Total Price Including Course and Dives: £300
