Enriched Air Nitrox  (40%)

The SSI Enriched Air Nitrox (40%) course teaches you how to safely plan and dive with nitrox mixtures up to 40% oxygen. This specialty is one of the most valuable upgrades for any diver — giving you longer no‑decompression limits, shorter surface intervals, and more efficient dive planning.

You’ll learn how to analyse nitrox cylinders, set your dive computer correctly, understand oxygen exposure, and make informed decisions that enhance both safety and enjoyment underwater. This course is classroom‑based with practical skills, making it ideal for divers who want to extend their bottom time without adding complexity to their diving.

How It Works

Classroom Session

Your instructor will guide you through:

  • Oxygen physiology
  • Maximum operating depth (MOD)
  • CNS and OTU exposure
  • Gas analysis and labelling
  • Dive computer setup
  • Nitrox dive planning

Practical Skills

You’ll practise analysing cylinders, confirming oxygen percentages, and applying nitrox planning rules to real‑world scenarios.
