A. Purpose
1. This Program is designed to provide Sport Divers with a safer breathing medium for enjoying dives in the 40 to 130 fsw (12 to 39 msw) depth ranges. The diver may elect to dive the "mix" on EANx tables, or dive conservatively using air dive computers or air tables.
2. The EANx Diver qualification may be taught as a single Program or combined with a variety of the Advanced or Specialty Diver Programs.
3. The Program covers the use of EANx mixes in the range of 21% to a maximum of 40% oxygen.
B. Prerequisites
1. Must be a qualified Open Water Diver.
2. Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 12 years of age for Junior Diver qualification, or a minimum of 18 years of age without guardian approval.
C. Program Content
1. Complete lectures from the Instructor presentation slides
2. Program covers all EANx mixes from 21% to a maximum of 40% oxygen, emphasizing the use of EAN 32 and EAN 36.
3. It is recommended that, all divers perform two dives on an EANx mixture of between 24 and 40% oxygen.
D. Program Limits
1. No dives may be conducted to depths greater than the student's previous qualification, or a maximum of 130 fsw (39 msw).
2. No dives having a mandatory decompression Stop exceeding 3 minutes may be made, unless the course is combined with Advanced EANx.
E. Qualification Requirements
1. Upon completion of the lecture portion and passing the written exam, the EANx Diver card will be issued.
F. Water Skills Development
1. If OW dives are made, the Instructor may elect to use the applicable EANx tables or plan the dives as if air were used, thus capitalizing on the maximum physiological safety factor.
2. If OW dives are made students must develop a dive plan appropriate for the mixes being used on both dives.
