Technical Diving International
Encyclopedia
Technical Diving International (TDI) is the largest technical diving
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.
TDI specializes in more advanced Scuba diving
techniques, such as diving with rebreather
s and mixed breathing gas
es, such as Heliox
.
TDI was founded in 1993 by Bret Gilliam
and Mitch Skaggs after a split away from International Association of Nitrox and Technical Divers
(IANTD) in 1993.
In 1999, TDI started a sister organization called Scuba Diving International
(SDI), which focuses on the recreational
end of Scuba diving
.
TDI subsequently started a further sister organization called Emergency Response Diving International (ERDI), which trains public safety diving (PSD) and trains police, fire and other public safety organizations in underwater search and rescue
techniques in a variety of submerged environments.
