This course is for advanced divers with proven experience in cave diving.
Minimum duration is 3 full days: lectures, confined water session, 4 stage cave dives.
The students learn the techniques and safety procedures to plan and conduct cave dives with the use of stage(s) cylinder(s) in order to extend the penetration over the range of the main gas volume.
Longer dives, more complex navigation and gas management make this course really challenging for cave divers.
