Which of the following is crucial for safety during night dives?

Using a compass and following pre-determined dive plans is essential for safety during night dives because visibility is significantly reduced in low-light conditions. A compass helps divers maintain orientation and ensures they can navigate effectively, preventing disorientation and potential loss of direction in the water. Following a dive plan is equally important as it helps divers stay aware of their location and the specific route they are supposed to follow, which is critical in low visibility situations.

Understanding the dive environment and having a clear plan allows divers to make informed decisions about their movements, depth, and duration of the dive. This reduces anxiety and increases safety, as divers are less likely to stray from their group or designated path. Recognizing the importance of structured navigation methods, as opposed to relying solely on natural cues or uncoordinated movements, contributes to a safer and more enjoyable night diving experience.
