CCR cave Diver

WHY TAKE THIS COURSE?

Venturing deeper into caves and discovering more and more passages may bring the need for additional time for exploration and redundancy for safety. Being an experienced open water GUE CCR diver and avid GUE cave diver will lead to consideration of using the CCR advantages during cave explorations. 

The GUE Closed-Circuit Rebreather Cave Diver course will prepare already experienced divers to safely use CCR technology while cave diving. 

WHO IS IT FOR?

The GUE Closed-Circuit Rebreather Cave Diver course is designed to provide experienced GUE cave and closed-circuit rebreather divers with the additional knowledge and practice needed to safely use closed-circuit rebreathers in a cave environment.

WHAT WILL I LEARN?

This course is an advanced level closed-circuit rebreather course aimed at teaching mastery level skills, knowledge, and procedures appropriate for the cave environment. 

Applicants for a GUE CCR Cave Diver course program must:

  • Be a minimum of 21 years of age.
  • Be physically and mentally fit.

    DPV CAVE

    The use of diver’s propulsion vehicles (DPV) or scooters has a long tradition in cave diving. DPVs are often used as an important tool to further increase the penetration distance or to carry additional heavy dive equipment into the cave.

    Since failure of a DPV in an overhead environment might expose divers to a high level of risk, an in-depth knowledge of gas management and contingency planning is required to use a DPV safely during such dives which DPV Cave course provides.

    UNDERWATER CAVE SURVEY

    Cave survey and cartography are highly important aspects of cave exploration and are useful for all advanced cave divers. In this special GUE class, divers will learn all the required skills to conduct a full survey of the cave starting from an in-water survey to drafting a map of the cave.

    During the class, team-based survey procedures and dive planning are introduced together with additional tools and specialized equipment.
