Full Trimix CCR

The Full Trimix course is the highest level of training in TEC diving and is required for all dives deeper than 75 meters.

Training content

In this course, you will no longer work on basic exercises, but must master all exercises to perfection and within the time limit. The aim is to prepare you for expedition diving and to train you in the necessary techniques, creating an awareness of how to return safely to the surface even from very deep dives.

Due to the high ambient and partial pressures, you have to carry out your planning and calculations very precisely. For dive planning, you work in the CCR Trimix area with an onboard base mix and various bailout travel and deco gases.

After completing the course, you must be able to plan and dive complex trimix dives with the rebreather, with several gas changes in the bail-out, in compliance with the gas laws.
