Trimix CCR Training
IANTD Trimix CCR Diver training, reflected in IANTD Spain?s Rebreather Trimix Diver page, is for rebreather divers already involved in deep diving who need full trimix capability on the unit they use. The official page explains that trimix is intended for divers who dive deep or need clearer performance at depth, and that the program requires a self-sufficient, self-reliant approach. For CCR divers, this means planning around helium-based diluent, oxygen control, decompression, bailout, and unit-specific risk management.
This course is not an entry into rebreather diving. IANTD lists Rebreather Normoxic Trimix Diver or higher as the prerequisite, along with a higher minimum age and proof of significant time on the rebreather to be used. Students should already be disciplined with CCR setup, monitoring, emergency drills, bailout strategy, decompression execution, and team communication before moving into deeper trimix ranges.
Training normally includes academic sessions, confined-water work, and open-water dives with emergency scenarios. In High Springs, Florida, Trimix CCR is a major step for divers preparing for demanding cave, wreck, or exploration objectives. The outcome should be a diver who can approach deep CCR trimix dives with better gas planning, more realistic bailout thinking, cleaner procedures, and a more conservative mindset from pre-dive preparation through debrief.
