IANTD CCR Diver training is a unit-specific closed-circuit rebreather course for competent divers who are ready to learn the safer use and technology of CCR diving. The IANTD Spain individual page describes the program as training divers for CCR dives requiring up to 15 minutes of decompression, with maximum depth depending on the student?s existing Advanced EANx or Advanced Recreational Trimix qualification. The course focus is equipment operation, CCR dive planning, oxygen monitoring, bailout thinking, and emergency discipline.
This is a serious rebreather course, not a casual try-dive. IANTD lists Advanced EANx Diver or higher, a minimum age requirement, and logged dive experience or instructor-confirmed readiness as entry requirements. Students should already have reliable buoyancy, strong gas-planning habits, and the patience to follow checklists and monitoring procedures exactly. Comfort with technical concepts is important because CCR diving adds task loading and removes some familiar open-circuit cues.
Training includes academic sessions, confined-water work, and open-water dives covering CCR planning, unit operation, survival skills, equipment configuration, and emergency scenarios. In High Springs, Florida, CCR Diver can be the first major step into disciplined closed-circuit training. A successful student should finish with a much clearer understanding of how to operate the unit conservatively, manage bailout, and keep rebreather procedures deliberate from setup through debrief.
