Why is it essential to have a clear ascent plan for night dives?

Having a clear ascent plan for night dives is crucial primarily to avoid disorientation and ensure safety upon surfacing. In low visibility conditions, such as during night dives, divers can easily lose their sense of direction. A well-structured ascent plan helps divers know where to go and what to expect as they ascend to the surface, ultimately promoting safety.

Understanding the surrounding environment, such as specific landmarks or designated markers for surfacing, is particularly important at night, when visibility is reduced. A clear ascent plan mitigates the risk of becoming lost or disoriented, thereby preventing potential accidents when returning to the surface. This enhances overall safety for all participants in the dive.
