TDI/SDI

Technical Diving International (TDI)

Now in its tenth year of business Technical Diving International is the largest Tech Agency in the world with over 10000 active Instructors. From it's humble beginning, TDI has now expanded to have regional offices in 45 countries worldwide.

TDI secured the first insurance coverage for both technical diving curricula and traditional sport diving limits in one policy. Currently TDI offers courses in Entry Level and Advanced Nitrox, Extended Range (deep air to 55msw), Entry and Advanced Trimix, Decompression Procedures, Rebreathers, Overhead, Advanced Wreck diving, and technician training for equipment servicing and the blending & mixing of gasses. TDI was the first to offer a fully developed training program for rebreathers and hosted the first ever instructor trainer workshop for that equipment in June of 1995.

Scuba Diving International (SDI)

Along with TDI, SDI the new division of the company was created to offer entry-level programs for new divers. SDI has already captured significant market share with its innovative approach to diver training. SDI recognizes the need for updated diver training that incorporates the use of modern diving technology. What does this mean for you, the SDI student? It means that you will use a personal dive computer throughout your in-water instruction and certification dives. Incorporating modern diving technology also means a more streamlined scuba course with more instruction time in the water, where it counts, instead of in the classroom. Diving with the latest, most sophisticated equipment means that you emerge as a scuba diver ready to confidently plunge in the 21st century.
