Advancev Recreational Trimix

Purpose

This Program is designed to extend the diver’s knowledge in the use of EANx/Trimix for Sport diving. It further develops diving skills and provides a greater understanding of the EANx concept of diving. It is also intended to supplement the skills of recreational trimix divers.

The Program employs EANx mixes from 21% to a maximum of 50% oxygen, and mixtures with a minimum of 28 % oxygen combined with a Helium content that maintains an END no greater than 80 fsw (24 msw) may be used.

This program qualifies divers to perform Trimix Dives outside of training up to 150 fsw (45 msw) and perform decompression stops required dives up to 15 minutes using EAN 50 as a decompression gas

Prerequisites

• Must be qualified as an IANTD Recreational Trimix Diver (covered inconjunction with this prorgam) 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.
• 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

• All Lecture and theory material must be completed.
• 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 150 fsw (45 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 150 fsw (45 msw). All dives deeper than 80 fsw (24 msw) must be made on recreational trimix mixtures.
• Students are taught the use of Recreational trimix mixtures from 25% to a maximum of 40% oxygen and with a helium content that maintains an END no greater than 80 fsw (24 msw) for diving. EANx mixtures in the range of 41% to a maximum of 50% oxygen are used to for safety and decompression stops.
