# Scuba Diving International

Scuba Diving International (SDI) is a Scuba training and certification agency. It is the recreational arm of Technical Diving International, a technical diver training organization.
SDI is a member of the United States RSTC, RSTC Canada and RSTC Europe.

## History

SCUBA Diving International, launched in 1998 or 1999, is the sister organization of Technical Diving International. SDI was created by dive professionals from the technical diving field. This gives the organization the perspective of teaching recreational diving through the lens of experienced technical diving.
SDI's philosophy is to improve recreational scuba diving training, enhancing older diving practices by incorporating new diving technology and emphasizing safety. The curriculum is set up to take divers from the beginner level to instructor level and structures its courses around a logged dive and specialty course approach. Divers who progress through SDI's recreational diving courses are then in a position to advance to technical diving with the courses offered by Technical Diving International.

## Training

Whereas TDI and ERDI (the two sister companies of SDI) handle technical diving courses and emergency personnel courses respectively, SDI covers the recreational aspect of diving by offering the following courses:
SDI requires students to have access to a modern dive computer on all dives during training from the very start.
SDI is also unusual amongst recreational diver training organisations in that it recognises solo diving as part of recreational diving, and offers a special training course relating to it. Most major recreational diver training organisations mandate diving with a "buddy" at all times.

### Entry Level Courses

These courses are meant for people interested in taking the first steps towards Scuba diving:
* Future Buddies Program - A course designed to provide children between the ages of 8 & 9 an introduction to scuba diving in a controlled environment under the direct supervision of an instructor. Once the future buddy turns 10 they can enroll in the SDI Junior Open Water Diver course.

* Open Water Scuba Diver Course - Entry-level certification to scuba diving
