Why take the CCR Cave Diver course?
Venturing deeper into caves and discovering more passages may require more time for exploration and added safety redundancy. As an experienced open water CCR diver and avid cave diver, you’ll want to use CCR advantages during cave explorations.
Who is it for?
The Closed-Circuit Rebreather Cave Diver course gives experienced cave and closed-circuit rebreather divers the knowledge and practice to safely use closed-circuit rebreathers in a cave environment.
What will I learn?
This advanced-level closed-circuit rebreather course teaches mastery-level skills, knowledge, and procedures for the cave environment.
