Recreational Trimix Diver

Complete Course Information

Recreational Trimix Diver

A. Purpose

1. This Program is designed to provide Sport Divers with a breathing medium for extending their dives to Sport Diving Depths by using ENDs in the 40 to 80 fsw (12 to 24 msw) depth ranges. The diver may elect to dive the "mix" on tables or computers.

2. The IANTD Recreational Trimix Diver qualification may be taught as a single program or combined with a variety of the IANTD Advanced or Specialty Diver Programs.

3. The Program covers the use of Recreational (Rec) diving mixes in the range of 28 to 40% oxygen with Helium content to provide an END no greater than 80 fsw (24 msw).

4. The program qualifies divers to do no stop required dives using Recreational Trimix Gas mixtures to a depth of 100 fsw (30 msw) or deeper up to students previous qualification level.

B. Prerequisites

1. Must be a qualified Advanced Open Water diver or equivalent and EANx Diver or take the EANx Diver course in conjunction with the Recreational Trimix Diver course.

2. Must provide proof of a minimum of 15 logged dives.

3. 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.

D. Program Content

1. Complete all lectures from the Instructor presentation slides.

2. Program covers all Recreational Trimix gas mixes from 28% to a maximum of 40% oxygen, and Helium concentrations yielding an END no greater than 80 fsw (24 msw) emphasizing the use of 28 / 25.

3. Two dives are required and must be on Recreational Trimix mixtures in this course.

4. It is recommend that this program be taught as a combined Deep Diver course or with the Advanced EANx Diver course with a minimum of two dives being completed on Recreational Trimix gas mixtures.

E. Equipment Requirements

1. Equipment used during this Program must be appropriate for the environment and in good working order.

F. Program Limits

1. No dives may be conducted to depths greater of 130 fsw (39 msw) and no END greater than 80 fsw (24 msw).

2. Appropriate safety decompression stops must be performed. {Safety stops will be at 30 fsw (9 msw) - 20 fsw (6 msw) and 15 fsw (4.5 msw) each stop will be a minimum of 1 minute}.

3. No dives having a mandatory decompression Stop exceeding 3 minutes may be made, unless the course is combined with Advanced EANx or Advanced Recreational Trimix.

4. No dives made me made with a PO2 greater than 1.6.

G. Qualification Requirements

1. Upon completion of the lecture, passing the written exam and completion of the dives satisfactorily the IANTD Recreational Trimix Diver card will be issued.

H. Water Skills Development

1. Complete a confined water session.

2. Demonstrate ability to plan Recreational Trimix dives.

3. Configure dive equipment for the most streamlined and efficient method.

4. Demonstrate good buoyancy control.

Advanced Recreational Trimix Diver Complete Course Information

Advanced Recreational Trimix Diver

A. 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. It is also intended to supplement the skills of recreational trimix divers.

2. The Program employs EANx mixes from 21% to a maximum of 50% oxygen. For divers qualified as recreational Trimix Divers mixtures of a minimum of 28 % oxygen combined with a Helium content that maintains an END no greater than 80 fsw (24 msw) may be used.

3. 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.

B. Prerequisites

1. Must be qualified as an IANTD Recreational Trimix 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.

C. Texts

1. IANTD Advanced Recreational Trimix Student Manual and Workbook, or equivalent text(s) approved in writing by the Board of Directors (written approval will be issued by IAND, Inc./IANTD World Headquarters).

D. Program Content

1. All Lecture and theory material must be completed.

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 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 r equirements 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.

3. Students are taught the use of Recreational trimix mixtures from 25% to a maximum of 40% oxygen and with a helium content with 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.

E. Equipment Requirements

1. A safety or decompression gas cylinder (if used) rigged as either a pony or stage cylinder. Gas cylinders must be oxygen clean and oxygen serviceable where needed.

F. 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 150 fsw (45 msw).

3. All dives must be conducted using EANx (maximum 40% oxygen). A higher EANx (maximum 50% oxygen) may be used at the decompression or safety stops.

4. All appropriate safety or required decompression stops must be performed.

5. Mandatory decompression stops are limited to a maximum of 15 minutes.

6. No dives made me made with a PO2 greater than 1.6.

G. Water Skills Development

1. A confined water session must be completed before conducting any OW dives.

2. Demonstrate proficiency in a variety of dive techniques and employ precision buoyancy control.

a. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) without a mask for a distance of at least 45 feet (15 meters), and commence gas sharing; or appropriate Rebreather gas management drill for out-of air diver. While gas sharing, swim for 3 minutes, then replace and clear mask.
