Technical Diving Classes

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

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)
