TDI Extended Range
The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers. The course cover topics like Equipment requirements, Dive planning, Oxygen tracking, Blending methods.
You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know.
TDI Decompression Procedures
As sport divers planned decompression is not something that we do or have been taught. The TDIDecompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, 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. Some of the materials you will be using include the TDI Divers Guide to Decompression Procedures, US Navy or Bühlmann Air Decompression Tables (made of vinyl for easy in-water use and storage).
TDI Extended Range
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/180 feet 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
- Materials for this course include the TDI Extended Range Diving Manual
TDI Trimix Diver
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/200 feet 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.
TDI Advanced Trimix Diver
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 / 330 feet 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
