The Enriched Air Nitrox Course is one of the most popular specialty certifications in diving. Nitrox allows you to dive with a higher percentage of oxygen and a reduced percentage of nitrogen compared to standard air — helping extend bottom time and reduce nitrogen loading.

What You’ll Learn

• How enriched air nitrox works and its advantages
• Oxygen exposure limits and dive planning considerations
• How to analyze tanks and set your dive computer properly
• Safe procedures for using nitrox blends
• How to maximize dive time while maintaining safety

Why Divers Love Nitrox

• Longer no-decompression limits
• Shorter surface intervals
• Reduced post-dive fatigue (many divers report this benefit)
• Ideal for travel and repetitive diving

Training Format

This course is typically completed through knowledge development and practical application. You’ll learn how to analyze cylinders and plan dives using nitrox safely and confidently.
