IANTD Semi-Closed Rebreather Diver training introduces competent divers to the safer use and technology of recreational SCR diving. The IANTD Spain individual page describes the program as no-decompression SCR training using EAN 32 to EAN 40, with dives limited to 70 fsw. The course is about understanding the unit, monitoring oxygen exposure, controlling buoyancy and trim, and learning the different habits needed when the breathing system is no longer simple open circuit scuba.
This course is suited to divers who want a structured entry into semi-closed rebreather diving without moving straight into deeper technical CCR work. The listed prerequisite is IANTD EANx Diver or equivalent, and the page notes that it may also be taken in conjunction with the SCR Diver class, subject to age requirements. Students should already be relaxed underwater, attentive to procedures, and willing to practice basic survival and emergency skills until they are clean and repeatable.
Training includes academic sessions, confined-water work, and open-water sessions. In High Springs, Florida, SCR training can be a practical first rebreather step for divers who want quieter diving, different gas efficiency, and better awareness of rebreather-specific responsibilities. The expected result is not just trying a new unit, but gaining a safer foundation in SCR operation, monitoring, buoyancy, and disciplined procedures.
