Advanced Nitrox

Our Advanced Nitrox course is designed for the diver who wishes to use gas mixes containing elevated percentages of Oxygen as either their primary diving gas or as a decompression gas.

This course builds upon the Enriched Air Nitrox course and examines the use of EAN 21 through 100% Oxygen for optimal mixes to a maximum depth of 130 feet. The object of this course is to train divers in the benefits, hazards and proper procedures for utilizing these mixes for dives not requiring staged decompression.

Why would you want to use mixes with higher percentages of Oxygen? As a primary gas used in shallow depths, Nitrox mixes greater than 40% allow substantially longer bottom times while greatly reducing your Nitrogen loading, thus reducing your DCS susceptibility. As a decompression gas, mixes up to 100% Oxygen can be used to shorten your decompression obligation, or during recreational diving profiles, to give you the added safety margin of increased Nitrogen out-gassing during your safety stops. Best of all, our course can be completed using single or double tank configurations.
