Yes, you need to be certified as an Enriched Air Diver prior to taking the Enriched Air Instructor Course. At EASE we conduct the PADI Enriched Air Instructor course. However, you do not have be certified as an Enriched Air Diver specifically through PADI. Any Enriched Air Diver certification, such as that offered by TDI, SDI or Naui, and many others is acceptable to meet the prerequisite. For those candidates who are not enriched air certified, we conduct the PADI Enriched Air Diver course concurently with the Enriched Air Instructor course.
