Normoxic Trimix CCR Training
IANTD Normoxic Trimix CCR Diver training, described by IANTD Spain as Rebreather Normoxic Trimix Diver, prepares qualified rebreather divers for helium-based mixed-gas dives between 130 fsw and 200 fsw. The program is intended for divers who do not want to breathe air below 130 fsw and who need safer rebreather procedures for normoxic trimix dives. The course focuses on mixed-gas planning, CCR monitoring, bailout thinking, decompression discipline, and managing narcosis with appropriate gas choices.
This course is for trained rebreather divers with real time on the unit they will use. The listed prerequisite is IANTD Rebreather Diver or higher, plus proof of logged rebreather dives and hours on the specific rebreather. Students should already be comfortable with CCR checklists, loop awareness, buoyancy, emergency drills, and ordinary decompression procedures before adding deeper trimix planning and the extra consequences of mixed-gas rebreather diving.
Training includes academic sessions, confined-water practice, and open-water dives with emergency scenarios. In High Springs, Florida, Normoxic Trimix CCR is a logical next step for divers who want deeper rebreather capability without moving directly into full trimix depths. The result should be more conservative planning, sharper unit awareness, better bailout decisions, and a clearer understanding of how helium changes the entire dive plan.
