SDI LogoScuba Diving International

Scuba Diving International (SDI) was created in 1999 and grew out of the success of it's sister company Technical Diving International (TDI), which specialises in the more advanced disciplines of dive training. Both students and instructors have embraced the no nonsense approach that the SDI training system offers. SDI has 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 agency to require students to be taught with modern dive computers from the onset of training.
