Cavern Diving
Definition
Cavern diving is a form of overhead environment diving where divers remain within sight of natural light and maintain direct access to the surface.
More on Cavern Diving
Cavern diving allows recreational divers to explore large, naturally lit spaces inside underwater caves or sinkholes while maintaining clear exit access. It differs from cave diving, which involves deeper penetration and greater risks. Specialized training is required for cavern diving, including navigation, guideline use, and emergency procedures. Equipment usually includes redundant lights, reels, and a backup gas source. Visibility, silt management, and staying within the light zone are key safety principles.
Frequently Asked Questions
Cavern divers stay within the daylight zone and have a direct path to the exit. Cave diving goes beyond visible light and requires advanced training, planning, and gear.
Yes. Cavern diving requires specific training due to the hazards of overhead environments and guideline navigation.
Redundant light sources, a primary reel with guideline, backup gas supply, and a helmet or streamlined setup are standard.
Yes, nitrox is common, especially for added safety during long bottom times or repetitive dives in cold water caverns.
Yes, but photographers must be careful not to silt the area or stray from the guideline. Using diffused lighting helps preserve visibility.
