Advanced Nitrox
This course examines the use of EAN 21 through 100%
(oxygen) for optimal mixes to a depth of
130fsw/40msw. 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).
Top
Advanced Wreck
This course provides the training and experience to
competently conduct advanced wreck dives,
penetration skills and techniques are covered.
Top
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 maximum depth of 150fsw/45msw
unless taught in conjunction with advanced nitrox,
Extended Range or Advanced Wreck Courses. The most
common equipment requirements, gear set-ups,
decompression techniques and decompression mixtures
(including oxygen and nitrox) are presented.
Top
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.
Top
Entry Level Trimix
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
200fsw/60msw.
Top
Advanced Level Trimix
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.
Top
Rebreather Training
This is the entry-level certification course for
recreational divers wishing to utilize a nitrox
semiclosed circuit rebreather (benefits, hazards and
proper procedures are comprehensively taught).
Top
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.
Top
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.
Top
Service Technician
This course enables the successful candidate to
engage in the preparation of scuba equipment for
technical diving gasses.
Top
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 course is
not intended to provide instruction for cave diving
environments.
