TDI

Technical Diving International

The Technical Diving International (TDI) diver training program is straight forward, proven effective and offers divers a comprehensive path from Intro to Tech™ to Advanced Trimix. Formed in 1994, TDI has built a reputation for a complete curriculum that includes cavern to full cave, decompression diving, trimix, and wreck penetration training. We also offer four levels of diver certifications on closed-circuit rebreathers to a depth of 100 metres or 330 feet. Round these offerings off with programs for gas blending and preparing equipment for oxygen service and the program selection is complete. Simply put, TDI is a one-stop technical training solution that you will not out-grow.
