Technical Diving

Why TDI?

Since 1994 Technical Diving International (TDI) has been the global reference in technical diving training. TDI’s training materials and standards are the most developed and complete in the diving industry, keeping the best safety record of all training agencies worldwide. TDI keeps every instructor and diver on a performance focus during the rest of their diving careers.

TDI Courses:

At Gili Divers we offer additional TDI courses for divers who wish to challenge themselves by pushing their limits a little further.

Intro to tech

TDI Intro to Tech Course is an introductory course that expands on recreational training by improving dive planning methods, in-water skills, and streamlining existing gear configurations in a controlled and fun learning environment.

Sidemount Diver

The TDI Sidemount Diver program is far more than just another “how to” book on sidemount diving. It’s a complete, comprehensive set of training materials designed to work together with our 3 open water dives. Improve your trim, be able to breathe more air during your dive. This course is a great preparation for further tech courses where the use of several tanks is beneficial.

Nitrox Diver

TDI Nitrox Diver Course is an entry level course for divers wishing to continue their diver education and utilize enriched air nitrox as a breathing gas to extend no decompression limits at depth

Advanced Nitrox Diver

Are you looking to expand your dive time? Maybe you’re a self-challenging diver or photographer looking to stay in the water a little longer? The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career.

Decompression Procedures Diver

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught. The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

Combined Advanced Nitrox and Decompression Procedures

The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.
