Description: For depths beyond 50 msw, the use of helium with normoxic oxygen (>18 %) to offset the high levels of nitrogen offers a major risk reduction. The Tri Mix Diver will have the ability to control both the narcosis and oxygen equations which must be considered when diving to these deeper depths. This is a diving and equipment intensive course requiring a high level of diving skill and experience prior to commencement.
