What you are going to learn

  • You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session you’ll:
  • Discuss managing oxygen exposure.
  • Practice analyzing oxygen content in your scuba tank.
  • Want to learn from home? We’re flexible! Choose the Elearning option and contact the store to schedule a 25 min “Quick Review” at your convenience.
  • Course total  Time: approx 3.5 hours

E-Learner Option

  • There is an e-learner option that will give you all the same information as we do in the full course. This can be purchased on our website and we will give you a code in the next five business hours to input on the PADI website where you can start your e-learning studies. 
  • Upon completion of the academics, schedule a time with us to come in to the shop to analyze a tank and write the final exam. This is typically a 30 minute process.


What You’ll Need?


  • Hold an Open Water Diver certification from PADI or equivelant from another recognized scuba diver training organization.
  • Be 12 years or older.


  • Since there are no dives involved in this specialty no equipment required, having said that it is recommended to have a diving computer to practice setting it to EAN mode. We will provide the tanks and analyzers for the practical hands-on session.
