What is a fundamental tenet of the buddy system in scuba diving?

The fundamental tenet of the buddy system in scuba diving is the principle of never diving alone. This is crucial for safety reasons, as having a dive buddy ensures there is someone to assist in case of an emergency, share experiences, and enhance the enjoyment of the dive. The buddy system allows divers to monitor each other’s air supply, provide assistance if one diver encounters difficulties, and facilitate communication underwater, which can be vital if unexpected situations arise.

In contrast, staying close to dive gear, carrying a whistle, or planning dives alone does not support the essential safety measures that the buddy system aims to provide. The buddy system fosters a sense of teamwork and accountability among divers, making it a cornerstone of safe diving practices.
