What is a key component of emergency preparedness for divers?

Carrying enough air supplies and signaling devices is a vital aspect of emergency preparedness for divers. Properly assessing air supply ensures that divers can manage their ascent and any unexpected situations they may encounter underwater. Having ample air not only allows for safety during the dive but also facilitates a controlled ascent if any issues arise.

Signaling devices further enhance safety by enabling divers to communicate their location or signal for help in case of emergencies. These can include surface markers, whistles, or mirrors, which can be crucial if a diver is separated from the group or needs assistance.

Preparation in both air management and signaling means divers are better equipped to handle emergencies, which is essential for a safe diving experience. In contrast, arriving late to dive sites can lead to rushed setups and increased risks, while only staying hydrated on land does not account for the physical demands of diving. Additionally, relying solely on a buddy's equipment compromises individual preparedness, as each diver should have their own functioning gear for emergency readiness.
