The TDI Advanced Trimix course provides
the training required to competently and safely utilise breathing
gases containing helium for dives that require staged decompression,
utilising Nitrox and/or oxygen mixtures during decompression
to a maximum depth of 90mtrs. The objective of this course
is to train divers in the benefits, hazards and proper procedures
of utilising custom oxygen/helium/nitrogen mixtures as breathing
gases. |
