NAUI Training Course

Tech Nitrox

OVERVIEW

This course is to provide the EANx certified diver with the skills and knowledge needed to minimise the risks of utilising optimal breathing gas EANx mixtures* of 28% through 100% (oxygen) for dives to a maximum training depth of 40 metres not requiring mandatory decompressions. (This course may be combined with the Decompression Techniques Diver Course. The resulting course would require ten dives for certification.)

*100% oxygen is used for decompression and 28% to 50% EANx is used for bottom mix in shallow water applications.

QUALIFICATIONS OF STUDENTS

Upon successful completion of this course, students are considered competent to utilise EANx mixtures 28% through 100% (oxygen) without direct supervision provided the diving activities and the areas dived approximate those of training.

PREREQUISITES FOR ENTERING THE COURSE

Minimum age of 18.
Minimum certification of NAUI EANx Diver and Deep Diver (or equivalent).
Proof of 50 logged dives with 10 dives on EANx.

SKILL REQUIREMENTS

At least four dives are to be made using EANx, at least one of which is to be a repetitive dive. The students are to analyse their own breathing gas mixture and plan and correctly execute each dive. Dive planning shall include limits based on gas consumption, oxygen exposures and inert gas loading for each dive and breathing gas mixture. If simulated or actual planned decompression stops are intended because of a combined technical EANx and Decompression Techniques Course on any dive, student divers must demonstrate use of an up line or lift bag and reel while performing simulated or actual stops. Student divers will participate in an emergency gas supply loss scenario at a depth not to exceed 18 metres, i.e. switch to separate redundant system and ascent to the surface. Students shall participate in a diver rescue situation to include management of a diver experiencing oxygen toxicity.
