About Technical Diving International (TDI)
TDI offers a comprehensive progression of courses that guide divers from the entry level of technical diving to the most advanced depths of exploration.
The TDI Intro to Tech course is an excellent starting point, providing tremendous value for those just beginning their technical diving journey. From this foundation, divers typically follow a three-step pathway into deeper, more complex dives:
TDI Advanced Nitrox and Decompression Procedures, or Advanced Nitrox and Helitrox combined TDI Trimix Diver
TDI Advanced Trimix Diver
Throughout your progression, TDI also allows you to specialize in areas that match your interests, such as DPV (Diver Propulsion Vehicle) Diving, Advanced Wreck, Sidemount, or even Gas Blending.
TDI also offers comprehensive instructor training for those looking to teach technical diving. Take a look at the TDI Flow Chart for inspiration and see how you can expand your diving skills and knowledge.
