Advanced EANx Diver

IANTD Certification Courses - Technical Diving

Purpose

1. This Program is designed to extend the diver’s knowledge in the use of EANx for Sport diving. It further develops diving skills and provides a greater understanding of the EANx concept of diving.
2. The Program employs EANx mixes up to 1.5 PO 2.
3. This program qualifies divers to do dive to 140 fsw (42 msw) and do decompression stops required dives up to 15 minutes.

Prerequisites

1. Must be qualified as an IANTD EANx Diver and IANTD Deep Diver with proof of a minimum of 30 logged dives or sufficient experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
2. Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 18 years of age without guardian approval.

Program Content

1. All lectures completed with IANTD Course-specific Slides pertaining to the theory in the IANTD Advanced EANx Diver Student Kit.
2. This Program must include a minimum of 120 minutes of OW bottom time completed within 4 dives, 2 of which must be to depths between 100 fsw (30 msw) and 140 fsw (42 msw) If combined with a Deep Diver Program, the total dive time for both Programs must include a minimum of 160 minutes completed within 6 or more dives. Even if the time and skill requirements are met within fewer than 6 dives, the minimum 6 dives must be made. If combined with a Deep Diver Program 3 dives must be made to depths between 100 fsw (30 msw) and 140 fsw (42 msw).
3. Students are taught the use of EANx mixtures to a maximum of 40% oxygen for the non decompression portions of the dive. To teach the fundamentals of safety and decompression stops EANx mixtures that contain 1.5 PO 2 for decompression may be used. This too, is calculated at the deepest depth to which the gas will be switched.

Program Limits

1. There may be no more than 4 students per Instructor. This ratio may be increased by 2 students for each assisting IANTD Divemaster, up to a maximum of 8 students with 2 IANTD Divemasters per class session.
2. No dives may be conducted to depths greater than 140 fsw (42 msw).
3. All dives must be conducted using EANx (maximum 40% oxygen). PO 2’s as high as 1.5 may be used at the decompression or safety stops. No dives made me made with any PO 2 greater than 1. 5.
4. All appropriate safety or required decompression stops must be performed.
5. Mandatory decompression stops are limited to a maximum of 15 minutes.
