A diver in an overhead environment must be self-sufficient and what other quality?

In an overhead environment, a diver must possess self-sufficiency, which refers to the ability to manage their own needs and decision-making without reliance on external assistance. In addition to being self-sufficient, the diver also needs to be self-honest. This quality is crucial because it involves recognizing one’s own skills, limitations, and the realities of the diving situation.

Self-honesty allows divers to accurately assess their own capabilities and make informed decisions about their safety, equipment, and the dive plan. It promotes a culture of safety and personal accountability, ensuring that divers are aware of whether they are fit to dive, understand their own emotional state, and can recognize when they may need to abort a dive or when they must rely on their dive buddies for assistance.

While the other qualities might contribute to a diver's overall effectiveness, they do not have the same critical impact in the context of diving in overhead environments. Self-motivation and self-awareness, while important, do not emphasize the necessity of recognizing one's own limitations and truth in high-pressure environments like cavern diving as directly as self-honesty does.
