What practice promotes group cohesion during night dives?

Frequent buddy checks and communication are essential practices that foster group cohesion during night dives. In low visibility and darkness, the risks increase, and maintaining close contact with dive partners enhances safety and strengthens the bond within the group. Regular buddy checks ensure that divers are aware of each other's equipment and well-being, while open communication allows for sharing experiences, addressing concerns, and coordinating movements in the water. This collaborative approach helps divers rely on each other, thereby promoting a sense of unity and teamwork, which is crucial in the challenging conditions associated with night diving.

The other options do not contribute effectively to group cohesion. Randomly splitting into pairs could lead to confusion and a lack of familiarity among divers, whereas diving independently undermines the principle of teamwork essential for safety. Taking turns leading the dive might be beneficial in certain contexts, but without consistent communication and checks, it may not necessarily promote unity during the dive itself.
