SDI
SDI was created in 1999 and grew out of the success of their 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. SDI has streamlined the course materials to let students study the essential academics with a renewed emphasis on practical diving skills learned in both the pool and open water environments. And SDI was the first agency to require student to be taught with modern dive computers from the outset.
