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 your TDI Instructor will also cover

• Equipment considerations
• Cylinder labeling
• Analyzing of Nitrox

The course follows an easy to read and understand diver manual titled Understanding Nitrox and water proof tables for quick on site reference.

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

• 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.

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

• 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 Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)

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

You will demonstrate proficiency in blending enriched air nitrox and the proper labeling of nitrox cylinders.

The TDI Nitrox Gas Blender manual will take you through the processes of blending nitrox in an easy to read and understand format. Additional support materials include the SDI/TDI Gas Blending Log.

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

The TDI Advanced Gas Blender manual will build your academic knowledge and act as a great resource manual for future reference. Also available is the SDI/TDI Gas Blending Log.
