TD Tec Diving with Trawangan Dive
Technical Diving International (TDI) was formed in 1994 by some of diving's most experienced instructors to bring technical applications of diving to a wider audience. TDI's training materials have become known as the industry's best and most professional resources.
 

Most importantly, TDI has the best safety record of all training agencies. TDI has become the largest international specialized dive agency.

Trawangan Dive offers a variety of TDI Nitrox, Trimix, Closed Circuit Rebreather (CCR) and Service courses.

Nitrox Diver

The TDI Nitrox course is an entry-level course for divers wishing to utilize enriched air nitrox as a breathing gas. Little else has impacted recreational diving more than the introduction of Nitrox, allowing more time underwater.
