Technical Diving courses
Here is an overview of the technical diving courses offered by TDI
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 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).
Advanced Wreck
This course provides the training and experience to competently conduct advanced wreck dives, penetration skills and techniques are covered.
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/45msw 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 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.
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.
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).
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 course is not intended to provide instruction for cave diving environments.
Introductory Cave
This course is an introduction to the basic principles of cave diving utilizing a single cylinder. Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern course.
Cave
This course is the third stage of training in the series of TDI’s cave diver development program. Advanced cave dive planning the practical execution of different types of cave systems and scenarios divers encounter are presented.
Technical Divemaster
This course is the third stage of training in the series of TDI’s programme. Advanced dive planning
