CCR Normoxic Trimix Diver

This program trains rebreather divers to conduct technical dives to depths between 130 fsw (39 msw) and 200 fsw (60 msw) without using air as a primary bottom gas below 130 fsw. It focuses on the application of normoxic helium-based gas mixtures (Trimix) to mitigate narcosis and gas density issues during technical rebreather operations.

Program Specifications

  • Maximum Depth: 200 fsw (60 msw)
  • Minimum Age: 18 years old
  • Prerequisites:
    • Must be qualified as an IANTD Rebreather Diver

    • At least 25 logged dives and 25 hours must be on the specific rebreather unit to be used in the course
    • At least 10 logged rebreather dives must be to a minimum depth of 100 fsw (30 msw) requiring staged decompression stops

  • Equipment Requirements:
    • Approved rebreather unit listed on the IANTD webpage
    • One (1) bailout cylinder
    • Two (2) decompression cylinders
