Discover Enriched Air Nitrox (EANx) and Enriched Air Nitrox (EANx) Specialty Course

PADI EANxProfessional Association of Diving Instructors (PADI)

Welcome to PADI's most popular specialties!

As nitrox contains less nitrogen and a higher percentage of oxygen than normal air, you'll absorb less nitrogen as you dive giving you longer no decompression limits. Diving with enriched air means more time underwater but you need to be certified as an Enriched Air Diver to get EANx fills.

Feeling curious about diving with Nitrox?

Join the Discover Enriched Air Nitrox program and give it a try! PADI DISCOVER Enriched Air NITROX consists of the following segments of the PADI Enriched Air Diver Specialty Course:

  1. Knowledge Development 1:
    Covering enriched air dive planning, care for equipment, hazard management, use and application of enriched air, and completing a Knowledge Review. You'll complete these requirements using DISCOVER Enriched Air NITROX Online. Sign up for Discover Enriched Air NITROX online by signing into My PADI Profile
  2. Practical Application 1:
    Using an oxygen analyzer to determine oxygen content in an enriched air blend, verification of cylinder content, use of a fill log. You'll complete these requirements with one of our Enriched Air Instructors at Arabian Diver

Join us in one dive and discover why diving with Nitrox is becoming THE NORM among divers.

Successful completion of DISCOVER Enriched Air NITROX will allow you to dive with enriched air blends with up to 32 percent oxygen. You'll be able make enriched air dives within the no-stop limits of the air Recreation Dive Planner (RDP) or an air-based dive computer, to a maximum depth of 30 metres/100 feet (depending on current certification level and experience), under the indirect supervision of a PADI professional (Divemaster, Assistant Instructor or Instructor) who is enriched air certified.


After receiving your DISCOVER Enriched Air NITROX certification, you can easily go on to complete the remaining requirements to attain the full PADI Enriched Air Diver certification. By doing so, you learn how to plan your dives accounting for oxygen exposure, and how to use enriched air dive computers and tables for planning dives within no stop limits and oxygen exposure limits. You'll also make at least two enriched air nitrox dives under the direction of one of our Enriched Air Nitrox Instructors. As a PADI Enriched Air Diver, you'll be certified to dive independently using enriched air Nitrox with up to 40% oxygen to extend your dive time beyond the no stop limits you have with air.
