Nitrox Diver Course

This is the entry-level certification course for recreational divers wishing to utilize enriched air Nitrox (EAN) as a breathing gas. The objective of this course is to train divers in the benefits, hazards, and proper procedures for using Nitrox mixes from twenty two (22) to forty (40) percent oxygen content.

Qualifications of Graduates.Upon successful completion of this course:

1. Graduates may engage in diving activities utilizing EAN-22 to EAN-40 without direct supervision.

The student must:

1. Be a minimum age of fifteen (15).
2. Have a Minimum certification of Open Water Diver or a current enrollment in an Open Water Diver course.

Course Structure and Duration

Open Water Execution:

1. Two (2) Nitrox dives are recommended but are not required.

 

Advanced Nitrox Diver Course

This course examines the use of EAN-21 through one hundred (100) percent oxygen for optimal mixes to a depth of forty (40) msw / one hundred thirty (130) fsw.
