Enriched air nitrox (EAN) is a breathing gas with a higher percentage of oxygen than regular air. It allows longer bottom times, shorter surface intervals, and reduced nitrogen absorption, which can add a margin of safety to repetitive dives.

No, you don’t need to be a certified diver to take the SDI Computer Nitrox course. This is why we include it as part of our Open Water certification classes! However, to officially receive your Nitrox certification, you will need to complete your Open Water, Junior Open Water, or equivalent diving certification first. This ensures you have the foundational skills needed to safely use nitrox during dives.

No, you don’t need to own any special equipment to take the Nitrox course. We provide rental dive computers for use during the class, ensuring you have everything you need to learn and practice effectively. Once you’re certified—or even during the course—our instructors can help guide you in selecting the right dive computer for your specific diving needs, so you’re fully prepared for your next adventure.

No pool or open water dives are required. Since breathing techniques remain the same as with regular air, the course focuses on classroom or online training to teach you how to use nitrox safely and effectively.

The course covers dive computer programming for nitrox, oxygen exposure limits, benefits and risks of nitrox diving, and dive planning for safety and efficiency.

You must be at least 18 years old (or 10 years old with parental consent) and hold an Open Water Diver certification or equivalent.

The course takes about an hour to complete and is typically finished in a single session, depending on the student’s pace. We offer flexible scheduling options, including Sunday mornings, Monday evenings, and Thursday evenings. For added convenience, we can also accommodate ad-hoc classes to fit your personal schedule.

Yes, you’ll complete an online exam to demonstrate your understanding of nitrox diving concepts and dive computer use.

Yes, the SDI Computer Nitrox certification is internationally recognized, allowing you to dive with nitrox at any dive operation worldwide. This certification covers nitrox mixtures of up to 40% oxygen, which is ideal for recreational diving. If you’re interested in diving with nitrox mixtures beyond 40%, we offer the TDI Advanced Nitrox Course to expand your skills and capabilities.

A medical is required for the SDI Computer Nitrox course to ensure your safety during all aspects of diving, including learning how to use nitrox. While the course itself doesn’t involve pool or open-water diving, it builds foundational knowledge for future nitrox dives. Since enriched air nitrox allows longer bottom times and reduces nitrogen exposure, it's essential to confirm you’re medically fit to dive and handle the physiological demands associated with scuba diving. Ensuring your health and safety is always our top priority.
