What is the "buddy system" in diving?

The "buddy system" in diving is a fundamental safety protocol designed to enhance the safety of divers by promoting teamwork and mutual assistance. Under this system, divers pair up to ensure that each diver has someone to supervise and help them during the dive. This arrangement allows divers to keep an eye on each other's well-being, monitor air supplies, and provide immediate assistance in case of an emergency, such as an equipment failure or medical issue.

Having a buddy increases the chances of a successful dive because divers can communicate and back each other up, mitigating risks associated with diving. It reinforces the importance of vigilance and support, especially in potentially hazardous underwater environments. The buddy system not only improves safety but also fosters a sense of camaraderie among divers.

On the other hand, the other options either misidentify the nature of the buddy system or relate to different aspects of diving. For instance, associating it with recreational activities for couples, advanced techniques, or methods to increase dive depths does not accurately reflect the essential focus on safety that the buddy system embodies.
