Helitrox Diver

OVERVIEW AND QUALIFICATIONS

This course is to provide the training and experience necessary to gain the knowledge and understand the hazards of utilizing helium enriched EANx mixes of 21%-30% oxygen and no more than 35% helium for dives to a maximum depth of 52m (170 ft.) that require staged-decompression, utilizing EANx mixtures and/or oxygen during decompression. Upon successful completion of this course, graduates are considered competent to plan and execute helitrox based dives that may require staged decompression and utilize EANx and/or oxygen for staged decompression without direct supervision, provided the diving environment, activities, areas dived, and equipment approximate those of training.
