What does the term "buddy breathing" refer to?

The term "buddy breathing" refers to sharing air between two divers in an emergency situation. This practice is critical in scenarios where one diver experiences a malfunction with their air supply or runs low on air. By sharing air, both divers can maintain their safety and extend their dive duration until they can reach the surface or a safe location.

This technique requires both divers to be trained and familiar with the procedure to ensure smooth operation during a high-stress situation. Effective communication and coordination are key components, making it essential for buddies to practice air-sharing methods before they find themselves in an emergency.

In contrast, the other choices describe concepts that do not align with the emergency air-sharing context. Some relate to activities or procedures that do not involve collaborating with a diving partner in a critical moment. Understanding buddy breathing is vital for divers, as it underscores the importance of teamwork and preparedness during underwater exploration.
