Technical/Trimix Courses

Technical/Trimix Courses


UTD’s Technical Diver program consists of a three step process - Technical Diver 1 (Tech 1), Technical Diver 2 (Tech 2), and Tech Gold. These 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 Tech 1 and Tech 2, divers are trained and qualified to dive to a depth of 160’/48m breathing Helitrox 25/25 and Trimix 21/35 and 18/45 with a single decompression gas of Nitrox 50 or 100% O2. Optionally, divers may train to use a stage bottle to conduct multiple technical dives in the same day. Tech 2 divers may also take Tech Gold, which allows two decompression bottles on a dive (Nitrox 50 and 02). UTD's Tech program limits divers to 30 minutes of decompression.

UTD’s Trimix Diver program, like the Tech diver program, is also a multi-step process, consisting of Trimix 1, Trimix 2, and Trimix Gold. 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 Trimix 1 and 2 into one 6-day class, if prepared.

Trimix 1 takes divers to 200'/60m with a maximum of one hour of decompression, Trimix 2 moves divers to 250'/75m with a 90-minute decompression limit, and Trimix Gold is our unlimited open circuit dive certification.
