TECHNICAL DIVING INTERNATIONAL (TDI)

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 dive in areas where only a small percentage of divers had been before. These includes Prince of Wales and HMS Repulse in South China Seas, cave diving Khao Sok and Sra Keow in Thailand, deep untouched reefs and unexplored caves in Indonesia and more!

TDI professionals are held to the highest standard to ensure quality training throughout the world. This means that as a diver taking a TDI course, your instructor will have documented his experience and knowledge prior to achieving that rating. As an instructor candidate taking a TDI course, your TDI instructor trainer would have gone through the paces to achieve the highest level of training that TDI offers.

TDI instructors and facilities are located throughout South East Asia. Whether you are looking for your next wreck, cave, sidemount or rebreather courses, we can certainly match a TDI instructor for you.
