TRIMIX I
UTD’s
Trimix Diver program, like the Tech Diver program, is a
two-step process, consisting of Trimix 1 and Trimix 2. This
building block concept adds depth and complexity in small steps,
building on a the technical diver’s existing skills. A student may
take these classes individually, allowing time between to gain
experience, or may combine them into one 6-day class if prepared.
At the completion of Trimix 1, the diver is qualified to 200’/60m
using all standardized bottom and decompression mixes and multiple decompression bottles. The

Class Information
While
the use of trimix is not tremendously complicated, there are many
subtle and potentially dangerous issues with which divers must be acquainted while trimix diving especially when utilizing multiple
decompression stage bottles. UTD believes that individuals in the
pursuit of trimix training should not be limited by the information
made available to them. Instead, the trimix diver should be privy
to all the practical and theoretical issues likely to be
encountered.
This class is structured around a 3 consecutive days structure. (The class may be combined with Trimix 2 for a 6 consecutive day class known as Trimix Diver.) Trimix 1 course involves a minimum of 6 hours of classroom instruction and 8 dives (4 practice dives, and 4 experience dives with Trimix with all 8 dives conducted with multiple deco bottles ), designed to provide a working knowledge of trimix, including an understanding of the history and practice of decompression, physics, physiology, table analysis, ratio deco (deco on the fly) and operational considerations. This class is a decompression class, so divers in this depth range must be prepared to enter decompression obligations.

At the completion of Trimix 1, the diver is qualified to 200’/60m
using all standardized bottom and decompression mixes and multiple decompression bottles. The
completion of Trimix 2 qualifies the diver to dive to 250’/75m using all standardized bottom and decompression mixes, multiple stage bottles and decompression bottles.
The UTD
Trimix Diver 1
course is designed to continue a diver’s pursuit of technical
diving, giving them the ability to use hypoxic trimix blends and to
carry and manage 2 decompression bottles (Nitrox 50 and
O2).
The limits of this certification will allow the diver to conduct
dives beyond the 160’/48m limits of the Technical Diver 2 certification.
New
material includes the nuances of trimix (hypoxic mixes), the gas
management and failure management of multiple decompression
bottles, the in-water management of these 2 decompression
bottles, 2:1 Ratio Deco and other academic issues and understanding of the dives
to 200’/60m.
This is a critical skills class. Failures will be introduced by the instructor to facilitate problem identification and resolution and building capacity and bandwidth for more progressively challenging diving.
The student will also incur significant mandatory decompression obligations on the experience dives in this course.
Who is this class designed for?
UTD
Trimix 1 is designed for the most demanding technical diver
who wants to explore beyond the 160' Tech 2 limits with multiple deco bottles.
This class instructs divers in the use/failures of doubles,
multiple stage decompression, trimix bottom mixtures and decompression
mixtures of 50% and 100% oxygen.
This class is designed to train and create competent and skilled trimix divers, explorers and team members. It teaches how to minimize risks and manage failures as a team. It creates confidence in emergency procedures and problem management and the ability to plan and execute a dive using hypoxic trimix.
This class is designed for those individuals who want to learn by doing, not just thinking. With an emphasis on practical, in-water training through development and simulation dives as well as experience dives, where the divers will plan, perform and execute their own trimix dives under the supervision of the instructor, this class builds safe, competent and skilled technical divers.
Why this class?
Trimix 1 is a mastery level class that reviews and refines skills
learned in the UTD Technical Diver combination, and continues to
challenge the student by introducing new procedures during the
descent, diving, and decompression phase of technical diving. This
robust course extends the diver's depth capability by introducing
the use of multiple decompression bottles as well as the use of hypoxic trimix.
The curriculum is designed to transform single deco stage technical divers into 2 deco stage technical divers, while introducing them to the demanding world that lies below the infamous “160 fsw (48m)” barrier and beyond the restraints of the decompression limits. Course participants will gain experience working with a variety of different gas mixtures for use as bottom mix and multiple stage and decompression gases. This information culminates in a true understanding of “best gas” selection and decompression from the 10 fsw (3m) to 200' fsw (60m) range and when combined with Trimix 2 (Trimix combination class) from 10 fsw (3m) to 250 fsw (75m).
Long-range dives can be very demanding, greatly exceeding “no-decompression” limits. As a result, gas management, oxygen management and decompression table analysis, ratio deco (deco of the fly) all become critical aspects to dive planning. Topics addressed in Trimix 1 course will build upon previously learned skills with an emphasis on staging, dive planning, accelerated decompression and technical equipment configurations. Practical sessions will involve a minimum of eight (8) dives while using double tanks and two decompression bottles. At least two of these dives will be conducted with trimix.

Day 1 - Typically we begin with a 3 - 4 hour initial session consisting of
introductions, and dry runs (on land) of the skills and some
practice before entering the water. Skills include improving a
divers understand of deco bottle handling, air sharing, valve
failure & management, ascent procedures and surface marker buoy
deployment. Students then have 4 dives putting these skills
and concepts into actual practice. We conclude with a video review
and a few hours of lecture.
Day 2 - The second day consists of dive planning and execution of repetitive deep dives (160'/48m- 180'/54m) using multiple deco bottles. These experience dives are videoed and reviewed.
Day 3 - The third day continues the dive planning and execution of repetitive deep dives (160'/48m-200'/60m) using multiple deco bottles. These experience dives are videoed and reviewed.
All UTD/FKD classes are videotaped for educational review, as we believe this is invaluable for students to visually focus on their individual in-water skills, situational awareness, communication, and team diving. Learning to self evaluate is an important aspect of any class, and video is one of the most important tools we have for instruction.

You will be evaluated during the class
to obtain the UTD "Trimix Diver 1" certification. This certification will allow you to dive within the course limitation
of 200'/60m while utilizing trimix 18/45 and 2 decompression
bottles of Nitrox 50% and Oxygen. It will also allow you to continue
into the UTD Trimix 2 training curriculum. Our focus is the
complete dedication to your diving skills, knowledge & in-water
practice.
