Technical Diver Program UTD’s Technical Diver program consists of a two step process - Technical Diver 1 (Tech 1) and Technical Diver 2 (Tech 2). They are building block classes that  introduce a diver to deeper depths and staged decompression in a slow progression, first working on bottom skills, then ascent skills and finally mid-water skills. Upon completion of these two courses, divers are trained and qualified to a depth of 160’/48m breathing Helitrox 25/25 and Trimix 18/45 or 21/35, the optional use of a stage bottle to conduct multiple technical dives in the same day, and to use a single decompression gas of Nitrox 50 or 100% O2. Technical Diver The Technical Diver combines the Tech 1 and Tech 2 programs into one class to prepare divers for the rigors of Technical (decompression) diving and to familiarize them with the use of various breathing gases, including 18/45, 21/35 or 25/25), use of two different decompression mixtures (Nitrox 50 or 100% O2), and the use of a stage bottle to conduct two technical dives in a day . Tech Diver training first focuses on critical skills with reference to the bottom, the on mid-water critical skills, simulating failures for the team to solve. This tests the team's ability to deal with failures not only on the bottom but also during the accent and gas switch – skills which are essential for safe technical diving. This critical training will include problem identification and resolution, and building the capacity for progressively more challenging diving.   Students will continue to use double tanks/cylinders and an optional single stage bottle and will discover the potential failure problems associated with them. You will  also use a deco bottle of either Oxygen or Nitrox 50 for accelerated and “on the fly” decompression and will take advantage of the use of Helium to minimize narcosis. The application and benefit of single decompression stage diving will be thoroughly explored. The class will focus on Helium-based breathing gases as flexible and beneficial choices for dives first to 130'/39m, then to 160’/48m while using a single decompression gas such as Nitrox 50 for both accelerated decompression and safe rock bottom planning. Prerequisites Minimum 18 years of age Minimum of 75 dives beyond openwater qualification UTD Tech 1 or equivalent Course Limits Maximum depth 160’/48m Standard back-gases are Helitrox 21/35 Standard decompression gases is either O2 or Nitrox 50 One deco bootle No overhead environments. Why this class? Technical Diver  helps you to understand the new reality of extending technical  (decompression) diving into the 160'/48m realm and conducting multiple technical dives in one day. With a focus on practical experience, stage use (for multiple dives in a day)  with simulated failures, our in-water time will focus on the myriad of issues that can make ascending from a dive more difficult. In the classroom, we'll focus on the planning and execution of technical dives, from the gas planning of deco gas (or loss thereof) to an extended discussion into the new ramifications of stage bottle use and decompression bottle use. During the first part of the class (Tech 1) we focud on developing your mind to address failures along the bottom and midwater with decompression on Oxygen. In this class, we'll focus on the ascent, stage bottle, Nitrox 50 and how to get you and your team home safely. Who is this class designed for? The second part, Technical Diver 2 is designed for divers who have experience with deeper diving with Helitrox 25/25 and Oxygen for decompression (1 deco bottle), but wish to extend their ability to a depth to 160'/48m on 21/35 or 18/45 and conduct multiple technical dives in the same day.  Adding an optional stage bottle allows you to extend your time and conduct multiple dives in one trip. With this class you will see more, experience more, and do more, whether it's photography, video, or simply enjoying the environment around you. Class Information This class is structured around 6 days, involving a minimum of eight hours of academics and eight dives, four of which will be critical skill dives and four will be experience dives, all designed to provide a working knowledge of Helium-based gases, including a discussions centered around gas management including stage bottle and deco bottle, use and understanding of deco tables for accelerated decompression, deco contingency planning including "Deco on the Fly," and more. As this course is a decompression class, divers in this depth range must be aware of the potential for entering into decompression commitments and should be prepared. 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 "Technical Diver" Certification. This Certification will allow you to dive within the Techncial Diver limitation of 160'/48m while using 21/35, 18/45 or 25/25 for bottom gas and Nitrox 50% or Oxygen (1 Deco Bottle)  for decompression. The class offers optional training in the use of a stage bottle use. It will also allow you to continue on to the UTD Trimix 1 training. Our focus is the complete dedication to your diving skills, knowledge and in water practice.
