Nitrox
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 22% to 40% oxygen content.

 

Advanced Nitrox
This course examines the use of EAN 21 through 100% (oxygen) for optimal mixes to a depth of 150fsw/45msw. The object of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN 21 through 100% (oxygen) for dives not requiring staged decompression. (Decompression techniques may be combined with this course at the discretion of the instructor).

 

Decompression Procedures
This course 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 maxium depth of 150fsw/50msw unless taught in conjuction with advanced nitrox, Extended Range or Advanced Wreck Courses. The most common equipment requirments, gear set-ups, decompression techniques and decompression mixtures (including oxygen and nitrox) are presented.

 

Extended Range
This course provides the training and experience required to competently utilize air for dives up to 180 fsw/55msw that require staged decompression, utilizing nitrox mixtures and oxygen during decompression.

 

Entry Level Trimix
This course provides the training required to competenly 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 200fsw/60msw.

 

Advanced Level Trimix
This course provides the training required to competenly 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.

 

Nitrox Gas Blender
The objective of this course is to train candidates in the proper technique equipment requirements and hazards involved in blending nitrox gases for recreational scuba.

 

Advanced Gas Blender
The objective of this course is to train candidates in the proper procedures needed for the preparation and blending of high quality gasses.

 

Service Technician
This course enables the successful candidate to engage in the preparation of scuba equipment for technical diving gasses.

 

Overhead Environment / Cavern
This course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; in addition outlines specific hazards associated with cave diving. The Cavern Diver Course in not intended to provide instruction for cave diving environments. The objective of this course is to train divers in the proper planning, procedures, techniques and hazards of cavern diving.

9.  Two (2) battery powered lights, each with burn time suitable for the planned dive time.
10.  Computer or watch (bottom timer) and depth gauge.
11.  Slate or wet notes and pencil.
12.  Submersible dive tables or backup dive computer (recommended).

Introductory Cave
This course is an introduction to the basic principles of cave diving utilizing a single primary guide line. Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern diver course. This introduction to cave diving is not intended to train divers for all facets of cave diving. The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.

The following equipment is required for each student:
1.  Primary cylinder (s) - volume appropriate for planned dive and student gas consumption.
2.  Dual-orifice (Y) or (H) closed valve or dual valve manifold.
3.  Two independent first and second stage regulators. One regulator equipped with a long hose at a recommended minimum length of two (2) meters / seven (7) feet.
4.  Submersible pressure gauge.
5.  Buoyancy Compensator with power inflator.
6.  Exposure suit adequate for diving environment.
7.  Mask and fins - NO snorkel.
8.  Line cutting device.
9.  Three (3) battery powered lights - one (1) primary and two (2) back-ups, each with a with burn time suitable for the planned dive time.
10.  Safety reel with a minimum of thirty (37) meters / one hundred twenty five (125) feet of guideline.
11.  One (1) primary cave-diving reel with length appropriate for intended dive.
12.  Computer or watch (bottom timer) and depth gauge.
