This course provides the training required to competently and safely utilize breathing gasses containing helium for dives that require staged decompression, utilizing nitrox and/or oxygen mixtures during decompression to a maximum depth of 300fsw/100msw.

The mixing of gasses to dive is a somewhat new area in the recreational dive field, especially to the deeper depths listed here. You must learn the proper procedures in order to be a competent diver.
