TDI Technical Diving Courses 

Advanced Nitrox / Decompression Procedures
Extended Range / Trimix / Rebreathers

TDI is the largest technical certification agency in the world.  As one of the first agencies to provide training in mixed gas diving and rebreathers, TDI is seen as an innovator of new diving techniques and programs which previously were not available to the general public.  Training with TDI has provided divers with the opportunity to see such wrecks as the Andrea Doria, Luisitania and the Prince of Wales.  TDI divers have explored underwater caves in Spain, Australia and Mexico and assisted as support divers on world record freedives done in the Red Sea.

Academy of Scuba’s professionals are held to the highest standard to ensure quality training throughout the world.  This means that as a diver taking an Academy of Scuba course, your instructor will have documented his experience and knowledge prior to achieving that rating.  The Academy of Scuba is committed to offering the highest quality training supported by the latest materials with the most up to date information and techniques.  TDI’s materials are written by authors that acutely conduct the type of diving they are writing about. Those same materials are update as technology and equipment change.

Basic Nitrox Diver
TDI Nitrox course is an entry level course for divers wishing to utilize enriched air nitrox as a breathing gas. Little else has impacted recreational diving more than the introduction of nitrox, allowing more time underwater. During this course, you will learn the benefits, hazards and proper procedures for diving with EAN 22 to EAN 40 [ More Info ]

Advanced Nitrox Diver
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 hat 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: (1) Equipment Requirements, (2) Dive Planning, (3) Oxygen Tracking and (4) Blending Methods.

Decompression Procedures Diver
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/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: (1) Kit set-up, (2) Equipment Requirements, (3) Decompression Techniques, (4) Decompression Breathing Gases, (5) Gas Management, and (6) 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 Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage) [ More Info ]

Extended Range Diver
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: (1) Equipment requirements and configuration, (2) Decompression options, (3) Use of surface marker buoys, (4) Buddy rescue, (5) Narcosis checks and management.

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: (1) Dive team planning, (2) Gas matching, (3) Cylinder labeling, (4) Surface marker deployment, (5) Equipment configuration, (6) Thermal protection options
