About SDI

SDI was founded in 1999 and was an extension of our successful of our sister company TDI, prostate that specializes in the more advanced disciplines of scuba diving.

Our students and instructors use a straight forward 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.

Diving is constantly changing. SDI staff 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.
