Technical Diving International (TDI)

TDI was formed in 1993, to serve the technical diving market with innovative new courses, that pushed the boundaries.

 TDI was founded in 1993 when three instructors split away from International Association of Nitrox and Technical Divers (IANTD). The agency aimed to provide training materials and education for specialized diving situations. Some courses offered by TDI include open circuit courses such as diving with Nitrox as well as Rebreather courses.  They also provide training for overhead environments like caves and wrecks, mixed gas training and were one of the first diving agencies to create a comprehensive insurance plan for technical diving instructors

In 1999, the International Training brand expanded their offerings by starting a sister organization known as Scuba Diving International (SDI) focusing on the sport side of scuba diving. In 2000, another sister organization was launched called Emergency Response Diving International (ERDI) to teach public safety diving to public safety organizations.

One of TDI’s main goals since its inception is to be an innovator in the technical diving market, providing the latest programs & techniques and altering the previously held perception that technical diving was too risky.  By 1993 a few technical diving organizations had begun to form to prepare professional divers for technical diving situations and TDI joined the market. TDI created a training mission to shed new light on traditional diving limits while offering courses that meet the standards set by the World Recreational Scuba Training Council.
