Cave CCR

The ISE Cave CCR is an advanced course offered by Innerspace Explorers (ISE) that prepares qualified divers to safely use closed-circuit rebreathers (CCR) during cave dives. This training builds on both cave diving and rebreather skills, emphasizing advanced navigation, risk management, problem-solving, and operating a CCR in overhead environments where direct ascent to the surface is not possible. The course is designed for experienced divers already certified in open circuit cave and CCR techniques, and focuses on specialized planning, bailout procedures, and long-duration dives in complex cave systems.
