TDI Technical Diving International

TDI Diving Courses


TDI is the most significant technical certification agency in the world.  Firstly, it was one of the first agencies to provide training in mixed gas diving and rebreathers. Also, TDI is an innovator of new diving techniques and programs which previously were not available to the general public. For instance, TDI has provided divers with the opportunity to see wrecks such as the Andrea Doria, Lusitania and the Prince of Wales.  Besides that, TDI divers have explored underwater caves in many countries including Mexico and assisted as support divers on world record dives.


Also, the professionals teaching TDI diving courses are held to the highest standard to ensure quality training throughout the world.  As a result, a diver taking a TDI course can be sure the instructor will have documented his experience and knowledge while achieving that rating.  Also, an instructor candidate can participate in a TDI Instructor Development Course (IDC) knowing the TDI instructor trainer will have gone through all the necessary paces to reach the highest level of training TDI offers.


Moreover, Technical Diving International commits to offering the highest quality training supported by the latest materials with the most up to date information and techniques.  On the other hand, Technical Diving International’s writers acutely conduct the type of diving about which they write. However, those same materials evolve as technology, equipment and techniques change.
