TDI Rebreather Intro to Cave Diver – CCR Cave Diving Foundations

The TDI Rebreather Intro to Cave Diver Course is designed to expand the skills learned in cavern training and introduce divers to the techniques required for safe cave diving while using a closed-circuit rebreather (CCR).

Cave diving is one of the most demanding forms of technical diving. Divers must maintain precise buoyancy control, disciplined team communication, and strict dive planning procedures while navigating overhead environments.

During this course, divers learn how to conduct limited cave penetrations using a continuous guideline system, while maintaining proper trim, propulsion techniques, and situational awareness.

The course focuses heavily on safety procedures, guideline navigation, and gas management while diving with a rebreather in overhead environments. These skills form the foundation for more advanced cave exploration and prepare divers for programs such as TDI Rebreather Full Cave Diver.
