As sport divers planned decompression is not something that we do or have been taught.
The TDI Decompression Procedures course prepares you for planned staged
decompression diving. With a maximum operating depth of 45m, this course is your first step beyond the normal sport diving limits. Your TDI Instructor will provide you with valuable information and skills, among the topics covered are:
• Kit set-up
• Equipment requirements
• Decompression techniques
• Decompression breathing gases
• Gas management
• Contingency planning
The TDI Decompressions Procedures course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels
Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m you won’t have to miss those dives.
The Extended Range course will cover topics and skills such as:
• Equipment requirements and configuration
• Decompression options
• Use of surface marker buoys
• Buddy rescue
• Narcosis checks and management

As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas.
While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 m with a blend of helium appropriate for the planned depth.
The course covers topics and skills like:
• Dive team planning
• Gas matching
• Cylinder labeling
• Surface marker deployment
• Equipment configuration
• Thermal protection options

The TDI Advanced Trimix Diver course is the top level of training for open circuit divers wishing to dive to depths as deep as 100 m utilizing hypoxic levels of oxygen (below 17 percent).
This course is perhaps one of the most informative and challenging and upon
completion you are among some of the most elite divers. Your TDI Instructor will teach you:
• Equipment management
• Multiple stage cylinder labeling and placement
• Complex decompression planning and contingency planning
• Dive team awareness and communication
• Gas monitoring and management
• Use of travel gasses
In the TDI Gas Blender Course, you will receive a foundation of skills and knowledge that is needed to blend enriched air nitrox for recreational divers. After covering academic subjects including
• Responsibilities of the gas blender
• Oxygen handling
• Gas production equipment and oxygen analyzing

Building upon the TDI Gas Blender Course, the next step is taken in the TDI Advanced Gas Blender Course where you will develop and master the skills and knowledge needed to produce custom mix gases for technical diving that include helium.
After a review of academic subjects such as
• Formulas
• Gas analysis
• Blending equipment
• Blending systems
• Oxygen handling
