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.
The 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.
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.
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.
The TDI Extended Range Diver Course provides the training and experience necessary including proper techniques, equipment requirements, and hazards of deep air diving, to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.
One of the major limiting factors of going deeper is narcosis. The TDI Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas.
