What steps should a diver take if they become disoriented in a cavern?

When a diver becomes disoriented in a cavern, remaining calm and simulating a controlled ascent if necessary is crucial for ensuring safety. Panic can lead to poor decision-making and increase the risk of accidents. By maintaining composure, the diver can evaluate their situation more clearly and recognize the best course of action.

If the decision is made to ascend, doing so in a controlled manner helps prevent rapid ascents that can lead to barotrauma or decompression sickness. It's essential that divers manage their buoyancy and ascent rate while keeping an eye on their surroundings, even in low-visibility conditions, to avoid obstacles and other potential hazards.

Developing a routine response to becoming disoriented also reinforces the importance of training and preparation in cavern diving, where visibility can be significantly compromised. The other options do not address the necessity of remaining calm and controlled in an emergency situation, which is paramount for diver safety.
