Purpose of Trimix Diver TDI Course
The objective of this course is to train the benefits, hazards and proper procedures of utilizing custom oxygen / helium / nitrogen mixtures as breathing gases. Gas mixes are not to have any less than 18 percent oxygen (O2).
The TDI Trimix course provides the training required to competently and safely utilize breathing gases containing helium for dives that require staged decompression, utilizing nitrox and / or oxygen mixtures during decompression to a maximum depth of 60 metres. This course is intended for gaining of knowledge and skills on planning and carrying out of decompression dives at the maximum depth of 60 m with the use of gas mixtures (containing helium) - TRIMIX. During the course, the participants will familiarize themselves with practical principles of decompression dives at the depth of up to 60 m with Trimix gas mixtures, will learn to plan and carry out multistage decompression stops with the use of several decompression gases.
