What should be created for deeper dives as a precaution?

A contingency plan is essential for deeper dives as it prepares divers for potential emergencies and unexpected situations that may arise underwater. This plan should outline specific actions to take in various scenarios, such as equipment failure, rapid ascent, or diver incapacitation. It helps to ensure that all divers in the group are aware of the protocols to follow and who is responsible for specific tasks in the event of a problem.

Developing a contingency plan emphasizes proactive safety measures, allowing divers to focus on their dive experience while having the assurance that they are ready to handle emergencies effectively. It enhances overall safety and coordination among the dive team, which is especially vital in the more complex environment of deeper dives, where risks increase and diver responses can be more critical.

Other choices, while beneficial in their own ways, do not provide the same level of structured response preparation specific to the challenges posed by deeper diving conditions.
