During the course your TDI Instructor will teach you all the necessary skills to conduct CCR dives utilizing Normoxic Trimix as a diluent gas with oxygen levels as low as 16 percent. The course will prepare you to plan and undertake dives to a maximum depth of 60 metres. In order to safely use Helium as part of your diluent gases it is important that you understand gas physiology and how oxygen, nitrogen and helium can affect your body.
