Large Stingray
NAUI Enriched Air Nitrox (EANx) Course
OVERVIEW

This is course is to provide the diver with the
information necessary to utilize EANx as a
breathing medium. The course may be taught
as a stand-alone specialty course to certified
divers or the knowledge and skills training
may be integrated into the NAUI Scuba Diver
course.

QUALIFICATIONS OF GRADUATES

Upon successful completion of this course,
graduates are considered competent to utilize
EANx in open water diving activities without
direct supervision, provided the diving activities
and the areas dived approximate those of
training.

COURSE POLICIES

Dives shall not exceed a depth of 130 fsw or 1.6 atm PO2 , whichever is less. No planned dives requiring actual decompression stops on the appropriate EANx tables are to be permitted. (Maximum PO2 of 1.4 is to be taught with 1.5-1.6 as contingencies.) This course may be taught as a NAUI Recognition Program if the open water training dives are not included. Recognition may be upgraded to EANx Diver certification upon completion (within six months) of the required dives under supervision of a NAUI EANx Instructor.

SKILL REQUIREMENTS

At least two dives are to made using EANx, one of which is to be a repetitive dive. The student is to analyze his or her own breathing mixture and to plan and safely execute each dive.

ACADEMIC REQUIREMENTS

The following topics are to be covered: history of nitrox as a breathing gas; Dalton’s law of partial pressures; physiology of oxygen and nitrogen; depth limits, advantages, disadvantages and risks of nitrox; oxygen toxicity; hazards and precautions of handling oxygen; the concept of Equivalent Air Depth; use of EANx with Standard Air Dive Tables; common gas mixing procedures; and gas analyzing procedures.

PREREQUISITES FOR ENTERING THE COURSE
Age: Minimum is 15 years.
Certification: NAUI Scuba Diver certification or the equivalent is required unless combined with the Scuba Diver course. The instructor is to ensure adequate student knowledge and capability before any open water training and shall use skill or other evaluations to do so.
HOW MUCH DOES IT COST?

The NAUI EANx Diver Course costs $150 per student for groups of 3 or more and private courses are available for $200 per student. We schedule students together for group classes whenever possible unless a private class is specifically requested. Military and Public Service discounts are also available.
