According to Exley, what should divers do if they encounter a problem during an overhead dive?

Staying calm and assessing the situation is crucial for divers encountering problems during an overhead dive. This approach allows for a more effective evaluation of the circumstances, enabling divers to make informed decisions. Panic can often lead to poor choices, escalating the situation further. By maintaining a composed mindset, divers can better identify the nature of the problem—whether it's equipment malfunction, disorientation, or environmental hazards—and determine the safest and most appropriate course of action.

Careful assessment includes checking equipment, evaluating gas supply, and considering the environment before making any moves. This proactive stance empowers divers to respond thoughtfully instead of reacting impulsively, which can be vital in overhead environments where conditions can change rapidly and visibility may be limited. Engaging in methodical problem-solving enhances safety and preparedness, ultimately contributing to a safer diving experience.
