The TDI Advanced Level Trimix Upgrade 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 100m. The objective of this course is to train divers in the benefits, hazards and proper procedures of utilizing custom oxygen / helium / nitrogen mixtures as breathing gases.

The course is scheduled over two days. Prior to beginning the course you will be given the 'TDI Advanced Trimix' workbook. As with all our training we ask you to complete the knowledge reviews before you arrive for your academic presentation. There is also a written exam and a kit orientation.
