What is the recommended maximum depth for cavern diving?

The recommended maximum depth for cavern diving is up to 30 meters (100 feet). This limit is established based on a number of safety considerations specific to the conditions typically found in cavern environments. Cavern diving involves navigating within underwater caves that, while not as challenging as deeper cave systems, still present significant risks due to limited visibility and the potential for disorientation.

At this depth, divers can usually maintain adequate buoyancy control and use standard recreational diving techniques while remaining within the limits of their training. The 30-meter threshold allows divers to explore a variety of cavern systems while ensuring they have sufficient air supply and can execute safe ascents in case of an emergency.

Greater depths can introduce additional risks such as increased air consumption, increased effects of nitrogen narcosis, and the potential for more severe consequences from an out-of-air situation or equipment failure. Therefore, sticking to the recommended maximum depth enhances overall safety and ensures that divers operate within their training capabilities and experience level.
