Nitrox/ EAN
Overview
Equivalency/Brevet: CMAS/GDL DTSA Nitrox / SSI SC-EAN Enriched Air Nitrox
At SUBEX we dive with air28, a light nitrox mix for which divers do not need to take an extra course.
The background is that the dive computers remain set to the mixture of 21% oxygen. So SUBEX divers only experience increased safety, while they are still allowed to dive up to the recreational dive limit of 40 meters. They do not extend their bottom time during the dive.
If you want to extend your bottom time during the dive by using the Nitrox mixtures 32 or 36 and minimize the risk of nitrogen narcosis, you should have a Nitrox diving certificate, which enables you to dive safely and healthily with the changed oxygen-nitrogen ratio.
Prerequisites
• Completed diving training (SUBEX-Diver, CMAS/VDST 1 Star, OWD SSI/PADI)
• 7 logged dives
• Minimum age 14 years
About the course:
- The goal of the special course is to analyze the Nitrox mixture, plan the dive, especially in terms of depth and duration, learn about the no-decompression limit and the maximum operating depth with the modified gas mixture.
- In order to properly plan, conduct and complete the dives, the breathing minute volume is discussed again, the air consumption is calculated, the minimum air reserve, the maximum depth and the bottom time are set before the dive.
- 2 theoretical sessions at briefing and debriefing: introduction to Nitrox diving, physics and physiology, equipment for Nitrox diving, gas logistics and planning.
- With only three additional Specialities, your SSI OWD becomes an SSI Advances Open Water Diver.
