Enriched Air (Nitrox) Specialty

Dive Longer with Sea Dwellers Dive Center

Want to stay underwater longer and reduce your surface intervals? The Enriched Air (Nitrox) Specialty Course at Sea Dwellers Dive Center in Key Largo is the perfect way to maximize your dive time and enhance every underwater experience. At just $225, this PADI specialty course is one of the most popular and valuable certifications you can earn as a diver.

Enriched air, also known as nitrox or EANx, contains less nitrogen than regular air, allowing you to absorb less nitrogen during your dives. This means longer no-decompression limits and shorter surface intervals—giving you more time to explore the ocean.

Why Take the Enriched Air Specialty Course?

The PADI Enriched Air Diver course is the most popular specialty course in the world, and for good reason.

By diving with enriched air, you can:

• Stay underwater longer
• Get back in the water sooner between dives
• Reduce nitrogen absorption
• Feel less fatigued after repetitive dives

This makes nitrox especially beneficial for divers who plan to do multiple dives in a day or travel to top dive destinations. Many liveaboards and dive resorts even recommend or require enriched air certification.

If you want to get more value out of every dive trip, this is one of the smartest certifications you can earn.

What You’ll Learn

The Enriched Air Specialty focuses on the knowledge and practical skills needed to safely plan and execute dives using nitrox.

Understanding Enriched Air (Nitrox)

You’ll learn how enriched air differs from regular air, including how higher oxygen and lower nitrogen levels affect your dive profile and bottom time.

Oxygen Exposure Management

While enriched air allows longer dives, it also requires careful management of oxygen exposure. You’ll learn safe limits and how to avoid potential risks associated with higher oxygen levels.

Analyzing Your Tank

One of the key hands-on skills you’ll develop is analyzing the oxygen content in your scuba tank using an oxygen analyzer. This ensures you always know exactly what gas you’re breathing.

Dive Computer Setup

You’ll learn how to properly set your dive computer for enriched air diving, allowing you to track your limits and stay within safe parameters.

Dive Planning with Nitrox

Understand how to plan dives using enriched air tables or computers, including managing no-decompression limits and maximizing bottom time safely.
