TECHNICAL 2 (TECH 2)
The Technical Diver 2 is designed to build on the student’s
Tech 1 skills and experience by preparing the diver to dive in the 130-160’
range, with the use of two helitrox breathing gases (25/25 or 21/35) and the
use of two different decompression mixtures (EAN50 or 100% O2). In keeping with “teaching the way we actually
dive”, a stage bottle is also added to allow the diver to conduct multiple technical
dives in a day on a single set of double cylinders. This can be a huge logistical benefit when conducting a project or expedition in remote areas. The stage bottle is not used to extend bottom
time.
During Technical Diver 1, we focused 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 gas switch and how to get you and your team home safely.
Who is this class designed for?
The 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 and conduct multiple technical dives in the same day. Adding the Technical Diver 2 component allows you to extend your depth by using 21/35 and conduct multiple dives through learning to use stage bottle for the dives and backgas for bailout, allowing you to see more, experience more and do more, whether it's taking pictures, video, or simply enjoying the environment around you.
Class Information
This class is structured around 3 days, involving a minimum of 8 hours of academics and 7 dives, 4 of which will be critical skills dives and 2 will be experience dives. All designed to provide a working knowledge of Helitrox, including 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" (ratio deco) and more. As this course is a decompression class, divers in this depth range must be prepared to enter into decompression commitments.
Day 1 - We begin with a 3-4 hour initial session consisting of introductions and dry runs of the skills & some practice before entering the water. Skills include improving a diver's understanding of ascent procedures, including SMB deployment, stage bottle use, deco bottle switching and decompression. Students then have 3-4 dives putting these skills and concepts into actual practice. We conclude with a video review and a few more hours of lecture.
Day 2 - The second day is much the same as the first, including dry runs on land, video review and more lecture on Helitrox, decompression history and strategies, table analysis and ratio deco.
Day 3 - The third day is centered around gaining experience in the environment. You will conduct 2 Helitrox dives to a max depth of 160ft (48m), the first using the stage bottle (backgas for bailout) and the second using just the backgas, followed by video debriefing and the review and test.
All UTD classes are video'd 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 2 Diver" certification. This certification will allow you to dive within the Technical Diver limitation of 160'/48m while using 21/35 or 25/25 for bottom gas and Nitrox 50% or oxygen (1 deco bottle) for decompression and stage bottle use. It will also allow you to continue on to the UTD Trimix 1 training curriculum. Our focus is the complete dedication to your diving skills, knowledge & in water practice. To help prepare for the rigors ahead, contact us.
UTD equipment configuration is designed to be simple, efficient, and consistent. To get the most from your class it is advisable that you take the course in a complete UTD style system. To better assist you in preparing for class, we have listed below our suggested equipment lists for the class. Please contact us if you have further questions about your equipment needs.

dives in a day on a single set of double cylinders. This can be a huge logistical benefit when conducting a project or expedition in remote areas. The stage bottle is not used to extend bottom
time.Tech 2 training focuses on critical skills in the bottom failures with a stage and mid-water cultivating, integrating and ultimately testing the diver’s mid-water skills and ability to deal with failures not only on the bottom but also during the ascent and gas switch – skills which are essential for safe technical diving.
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.
Students will continue to use double tanks/cylinders and a single decompression
bottle of EAN50 for accelerated “on the fly” decompression and will use helium
to minimize narcosis. Stage bottles, and
the potential failures associated with them will be discussed in depth. The application and benefit of single
decompression stage diving will also be thoroughly explored.
The class will focus on Helitrox 21/35 as flexible and beneficial breathing gas for
dives to 160’/48m while using a single decompression gas such as Nitrox 50 for
both accelerated decompression and safe rock bottom planning.
Why this class?
Technical Diver 2 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.
