If a diver loses their buddy or guideline during a wreck dive, what should they do?

Remaining calm and looking for other divers' lights or the entrance is the most appropriate response if a diver loses their buddy or guideline during a wreck dive. This approach emphasizes maintaining a composed mindset, which is crucial in managing the disorientation that can occur in underwater environments, especially within confined spaces like wrecks.

By staying calm, the diver can think clearly and make sensible decisions. Actively looking for other divers' lights can help re-establish contact with a buddy or find other divers in the vicinity, who might provide assistance or guidance. Additionally, searching for the entrance to the wreck can help the diver orient themselves and navigate back to safety.

This response encourages divers to utilize their situational awareness and the skills they have been trained in. It also promotes safe diving practices by not rushing into potentially hazardous situations, such as searching the wreck independently without proper awareness of surroundings.
