In cavern diving, what is a 'limited entry'?

In the context of cavern diving, 'limited entry' refers specifically to not penetrating beyond the light zone, meaning that divers remain within a well-illuminated area near the entrance of the cavern. This approach is essential for maintaining safety and ensuring that divers have a clear reference to the exit points, which is crucial in the event of disorientation or equipment issues. The light zone serves as a visual guide, and staying within this area minimizes risks associated with deeper, darker sections of the cavern.

The term emphasizes the importance of being aware of the environment and the limitations placed on divers to enhance safety. Remaining within this designated area allows divers to enjoy the beauty of the cavern system while reducing the inherent risks associated with deeper dives, including potential disorientation, equipment failure, or getting trapped. Therefore, it establishes a clear boundary for what constitutes safe cavern diving practices.
