Advanced Nitrox/Deco Procedures

Is this one course or two? Technically, it is two separate courses — although almost no one ever teaches it that way.

Advanced Nitrox examines the use of EAN-21 through 100 percent oxygen for optimal mixes to a depth of 40 metres / 130 feet. The objective of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN-21 through 100 percent oxygen for dives not requiring staged decompression.

Decompression Procedures examines the theory, methods and procedures of planned stage decompression diving. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 metres / 150 feet. The most common equipment requirements, equipment set-up and decompression techniques are presented. Students are permitted to utilize enriched air nitrox (EAN) mixes or oxygen for decompression provided the gas mix is within their current certification level.

Instructors typically treat this as just a single course — one designed to take divers with no formal training in deco and teaching them how to make decompression dives to depths of 45 m/150 ft.

Students would take this program as a stand alone if they were preparing to make deep-ocean dives, but had no interest in going in caves.

Cave students typically take this course in combination with our Full Cave Diver program. Doing so saves considerable time and money.
