Who this class is designed for?

Many Rebreather Divers find themselves seeking more knowledge on how to apply UTD/DIR to their Rebreather configuration and how to apply the skills and knowledge to the Rebreather Diving. This class is designed for the rebreather diver who eager to learn some basic UTD/DIR diving skills and knowledge which can help improve their rebreather diving and/or wants to begin building a strong foundation to start pursuing the challenge of technical and trimix diving while incorporating UTD/DIR principles on their rebreather.


Why Take this Class?

Maybe you want to learn something new (like the UTD/DIR configuration) or you want to improve your safety by learning to do horizontal air sharing drills. Regardless of your motivation, in this class you will be introduced to the UTD/DIR diver's toolbox which you can then apply to your Rebreather Diving. You will learn to hover motionless, move forward and backward, turn around without disturbing the bottom. You will learn to air share open circuit bail out gas with your teammate in a reasonable and efficient manner. You will learn to ascend, making appropriate stops while deploying a surface marker to alert the boat and support team of you location and basic use of a deco/bailout bottle. In the classroom, rebreather divers need to know which gas to choose and why, how to plan a dive, from the back of the truck to a bench on the boat, and how to ensure that everyone has a great time and gets home safely. The Essentials of UTD/DIR Rebreather Diving isn't about showcasing the latest equipment, or rushing you into the next class. It's about working to develop skills that will improve your rebreather diving, and thus propel into a world of exploration.

Class Information

The Essentials of UTD/DIR Rebreather Diving class is designed to be taught over a three day period, with 8 hours of class and 4 open water dives.

Day 1. Typically the class begins with a 3 - 4 hour initial session consisting of introductions, covering the power point presentation including video tape of the skills to be evaluated throughout the class. Following a break for lunch and then a 3-4 hour of hands-on equipment fitting, review of gear configuration and a discussion of the pro’s and con’s of various equipment choices. Once the gear in properly fitted and configured the class then focuses on the “dry runs” of the skills and some practice before entering the water. Dry runs allow the student to practice the skills on land, before entering the water, under the watchful eye of the instructor(s). Skills include evaluation of divers trim, proficiency and precision buoyancy control, perfecting propulsion techniques (including learning how to kick backwards), fine-tuning equipment configurations, refining underwater communication, utilizing a team diving approach, and effective dive planning

Day 2. Begins with students conducting two dives, putting the skills and concepts discussed the previous day into practical use while the instructor demonstrates and the videographer captures the in-water session for review and evaluation after lunch. We conclude the day with a 1-2 hour video review where the performance is analyzed, with long discussions on how to improve. Finally, 2-3 hours of lecture brings the day to a close.

Day 3. The third day is similar to the previous day wherein the student will commence with conducting the additional skills and improving on the prior days performance, during two more dives which will again be video taped for subsequent review. The last dive of the class is an evaluation dive, where their performance will be analyzed and evaluated. After lunch the class will conclude with video review, final will lecture session and student performance review and final evaluations.

All UTD 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 "Essentials of UTD/DIR Rebreather Diving" Certification. Our focus is the complete dedication to your diving skills, knowledge & in water practice.
