Do you love exploring the underwater world but wish you could have more time to explore? Are you dreaming of extended ‘no decompression’ limits? If so, then this is the perfect course for you to learn how.

This popular specialty course is specifically designed to introduce and familiarize students with the benefits and diving procedures of using nitrox as a breathing gas. We will teach you how to plan and perform your dives and how to select the best possible mix of nitrogen and oxygen.

Nitrox is simply air with more oxygen in it, it will increase your available time underwater, increase your ‘no decompression’ limits, decrease your surface interval time and leave you feeling less tired as compared to diving with air.

You gain the biggest benefits from this course when combined with the SSI Deep Specialty. The nitrox course is land-based, and as such does not include dives unless combined with another course or fun dives. On this course you will learn to use and analyse enriched air as a breathing gas, to plan your dive and dive your plan with nitrox, and understand how nitrox affects you beneath the surface.
