Notifying a third party of plans is a crucial dive planning element for communication in case of emergencies because it ensures that someone outside the diving team is aware of the dive activities, location, estimated return time, and any special considerations. This person can serve as a point of contact and may initiate a search or alert authorities if the divers do not return on schedule. Clear communication with a third party enhances safety and accountability, providing a backup plan in case of unforeseen circumstances, such as getting lost or experiencing medical emergencies.

In contrast, choosing a dive site focuses more on the environmental factors of the dive, while selecting dive gear pertains to the equipment used, and deciding on dive depth relates to the safety and planning of the dive itself. While these elements are important for ensuring a safe dive experience, they do not directly address emergency communication in the same way that notifying a third party does.
