TDI Closed Circuit technical diving represents the pinnacle of advanced underwater training, designed for divers seeking to surpass conventional boundaries through closed circuit rebreather (CCR) technology. This discipline allows for deeper, quieter and significantly longer dives while maximizing gas efficiency and expanding technical exploration capabilities.
Through progressive, highly specialized training, divers learn to master advanced rebreather configurations, PPO2 control, bailout procedures, decompression planning, gas management and emergency protocols under internationally recognized standards. Each level is structured to build precision, autonomy and confidence in some of the world’s most demanding diving environments.
TDI Closed Circuit programs combine advanced technical theory, intensive confined water development and real-world open water application, preparing highly qualified divers for deep exploration, technical operations and complex missions with superior safety and performance.
