You love the UW world and want to stay longer? Then join us and do the Nitrox specialty course. You will learn to dive with more oxygen and less nitrogen - see more, experience more, stay longer! Take part in an Enriched Air Nitrox Specialty course if you want to shorten your surface intervals and extend your diving time. You'll spend more time exploring your favorite dive sites instead of waiting! With the course you will expand your diving knowledge to plan safe dives with enriched air mixtures up to 40% oxygen. After completing the course, you will receive an SSI Enriched Air Nitrox certification for 32% or 40%.
