What should a diver do before entering a cavern?

Checking equipment and dive plans with a buddy is crucial before entering a cavern. This step ensures that both divers are aware of each other's equipment status, dive objectives, and emergency protocols. Cavern diving presents unique challenges due to limited visibility and overhead environments, making clear communication and thorough planning essential for safety.

When divers collaborate on checking equipment, they can address any potential issues, such as equipment malfunctions or inadequate air supply, before the dive begins. Additionally, reviewing the dive plan together fosters mutual understanding regarding entry and exit points, depth limits, and how to handle potential emergencies. This collaboration strengthens buddy teams and enhances overall safety while navigating the unique environment of a cavern.

While considering water temperature or the presence of other divers may be important, these factors do not directly contribute to the safety and preparedness that checking equipment and diving plans provides. The use of a dive light or camera is also secondary to the fundamental need for safety and communication before embarking on a cavern dive.
