The primary purpose of the buddy system in scuba diving is to ensure safety and assistance between divers during a dive. This system establishes a partnership where each diver monitors the other's welfare, providing support in various situations such as during descent, ascent, or in case of an emergency. The buddy system enhances safety by allowing divers to keep an eye on each other’s air supply, buoyancy control, and overall attitude while underwater.

While designating a dive leader, improving underwater navigation skills, and enhancing equipment sharing may be incidental benefits or aspects of diving, they are not the main focus of the buddy system. The core objective remains centered on mutual safety and assistance, which is vital for managing the risks associated with scuba diving. By having a buddy, divers can react to any unforeseen circumstances together, promoting a safer diving experience.
