SDI WAS CREATED IN 1998 AND GREW OUT OF THE SUCCESS OF OUR SISTER COMPANY TDI, WHICH SPECIALIZES IN THE MORE ADVANCED DISCIPLINES OF DIVE TRAINING.
Both students and instructors have embraced the no nonsense approach that the SDI training system offers. We have streamlined the course materials to let students study the essential academics with an emphasis on practical diving skills learned in both the pool and open water environments. SDI is the only scuba training and certification agency to require students to be taught with modern dive computers from the onset of training.
SDI course materials are state-of-the-art; the materials are lavishly illustrated with photography and graphics.
Diving is constantly changing. SDI is always looking forward and striving to be the innovators in scuba diving education. SDI focus is to make the experience of diving one that is enjoyed by every family member.
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 see such wrecks as the Andrea Doria, Lusitania 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’s 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 will have gone through the paces to achieve the highest level of training that TDI offers.
TDI is committed to offering the highest quality training supported by the latest materials with the most up to date information and techniques. TDI’s materials are written by authors that acutely conduct the type of diving they are writing about. Those same materials are updated as technology and equipment change.
