What does the term "buddy system" refer to in scuba diving?

The term "buddy system" in scuba diving refers to the practice of pairing divers to enhance safety and provide assistance during dives. This system ensures that each diver has a partner who can monitor their safety, assist in emergencies, and help with navigation. Having a buddy allows divers to look out for one another, share air in case of an emergency, and offer support for various tasks underwater, such as checking equipment or pointing out marine life. This method is fundamental to safe diving practices, as it encourages teamwork and preparedness for unexpected situations, ultimately reducing the risk of accidents.

While documentation, advanced techniques for solo diving, and guidelines for choosing dive locations all play a role in diving as a whole, they do not encompass the primary focus of the buddy system, which is fundamentally about ensuring safety through companionship and mutual care during dives.
