Trimix II Diver
This course is to provide the diver with the experience and knowledge needed to minimize the risk of diving beyond 73m (240 ft.) while utilizing helium-based trimix breathing mixtures, hypoxic trimix breathing mixtures, helium based and EANx-based travel gases as well as EANx and oxygen during decompression.
Upon successful completion of this course, graduates are considered competent to plan and execute a team-based technical dive that requires travel gasses, staged decompression, helium based trimix breathing mixtures, and EANx and/or oxygen for decompression without direct supervision for dives that exceed 73m (240 ft.) provided the diving activities and the areas dived approximate those of training.
Minimum age is 18 years of age and graduate from a NAUI Trimix I course or equivalent is required for all continuing NAUI Technical Diving courses. Additional training and experience requirements vary for each course. A qualified NAUI Instructor can evaluate your resume and answer questions about your readiness to pursue specific training.
Continue your training by enrolling in a NAUI Technical course.
