PADI Enriched Air (Nitrox) Diver Specialty Course

The PADI Enriched Air (Nitrox) Diver Specialty Course is the most popular PADI specialty course worldwide, and for good reason.

Enriched Air Nitrox contains a higher percentage of oxygen and less nitrogen than standard air. By reducing the amount of nitrogen absorbed by your body during a dive, nitrox can help increase no-decompression limits on certain dives and reduce nitrogen loading during repetitive diving.

For many divers, this means more flexibility when planning dives, longer allowable bottom times and feeling fresher after multiple dives over consecutive days.

The course is particularly valuable for divers planning dive holidays, liveaboards, wreck diving trips and intensive diving programmes where multiple dives are conducted each day.

During the course you'll learn:

The benefits and limitations of enriched air nitrox
Oxygen exposure and safety considerations
Nitrox dive planning procedures
Analysing nitrox cylinders
Using oxygen analysers correctly
Setting dive computers for nitrox use
Maximum operating depth (MOD) calculations
Oxygen percentage verification
Safe nitrox diving practices
Equipment considerations for nitrox diving

The programme combines theory, practical exercises and hands-on cylinder analysis training, ensuring you can confidently and safely use enriched air nitrox on future dives.

Unlike many specialty courses, there are no mandatory training dives required, making this one of the quickest and most valuable certifications you can earn.

Upon successful completion, you'll earn the internationally recognised PADI Enriched Air Diver Specialty certification, allowing you to dive using enriched air nitrox within the limits of your training.

Many liveaboards, dive resorts and technical diving pathways strongly recommend or require nitrox certification, making this one of the most useful certifications a diver can hold.

Whether you're diving local wrecks, exploring the Red Sea, joining a liveaboard or simply looking to maximise your diving opportunities, the Enriched Air Diver Specialty Course will help you get more from every dive.
