What should divers communicate before beginning their descent?

Communication before beginning a descent is crucial for the safety and efficiency of the dive operation. The correct choice emphasizes the importance of discussing their readiness and the dive plan. This should include confirming that all divers understand the dive objectives, the planned route, safety procedures, and potential hazards they may encounter underwater.

Being clear about the dive plan ensures that all team members are aligned and can respond cohesively to any changes or issues that arise during the dive. Readiness involves assessing whether each diver is equipped, physically and mentally prepared, and aware of their responsibilities during the dive, contributing to a safer diving experience.

Discussing their personal dive certifications, individual skills, or planned depth, while also important, does not encapsulate the overarching need for team synchronization and agreed-upon operational guidelines necessary for the dive.
