Professional Association of Diving Instructors (PADI) is a popular name amongst scuba divers.

This community of diving instructors offers a wide range of courses and certificates of different levels. Do you love taking pictures underwater? Do you love the feel of the ocean spread all around you? PADI is just the place for you.

Famous for its eclectic recreational specialty courses, PADI offers an Enriched Air Diver certification. This is one of the most preferred and popular specialty courses. It gives you the benefit of using Nitrox, which is safer and better than normal gas. This special course also offers you more learning opportunities.

If you do not know much about this enriching course, you’ve got nothing to worry about. We are here to guide you through the PADI specialty Enriched Air Diver certification.

What Is Enriched Air?

To understand the meaning of enriched air, we need to dive into a few details. Enriched air is also called ‘Nitrox.’ As its name suggests, it refers to a mixture of nitrogen and oxygen, and it is a type of breathing gas. It may contain anything between 21-40% of oxygen and has a lower percentage of nitrogen than air.

Since nitrogen absorption is lowered, it extends divers’ no-decompression limits or commonly known as dive time. If a diver indulges in diving more than once a day, nitrox is especially useful. Nitrox divers have also reported having more energy than when they use air. It also protects you against decompression sickness.

Enlisting for the Enriched Air Diver certification and going through with the course will be a memorable and enriching experience.

Tips for Enriched Air Diving

You need to plan your dive properly. Firstly, your equipment must be approved and safe to use. Ensure that you buy a nitrox-enabled dive computer to make your dive easier. If you are repeatedly diving, make sure you reset your dive computer before every dive, as many dive computers require it.

The most popular and trusted mixes for enriched air are Nitrox 32 (32% oxygen and 68% nitrogen) and Nitrox 36 (36% oxygen and 64% nitrogen). They are the safest ones to choose from.

In case your dive computer fails, which is a rare occurrence, it is good to have a backup. You may bring your dive table underwater for easy reference. Also, handle your scuba tank with care and clean it properly to avoid any explosions.
