Scuba Diving International

SDI started the journey in 1994 with the founding of Technical Diving International (TDI), one of the first agencies dedicated to providing specialized diving training. TDI set the standard for technical diving education, offering comprehensive programs for advanced diving techniques, including Nitrox, Closed Circuit Rebreathers, and overhead environments like caves and wrecks. As the ultimate one-stop solution. for technical divers, TDI established a foundation that would soon expand into new areas of diving education.

With 26 Regional Offices servicing more than 100 countries, the company today far exceeds the original vision the founders had when they conceived the idea on a napkin, sitting at a kitchen table in the early 1990’s.
