What is the purpose of a "buddy check" and when should it occur?

The purpose of a "buddy check" is fundamentally about ensuring safety through mutual equipment review and verification before both divers enter the water. This procedure is crucial as it allows divers to identify any potential issues with their gear, such as checking for proper fit and function of equipment like tanks, buoyancy control devices, masks, and fins.

Conducting a buddy check prior to the dive helps to confirm that both divers have everything they need and that their equipment is functioning correctly. This collaborative process not only builds trust between buddies but also enhances overall safety, thus preparing both divers for a successful underwater experience.

While monitoring air supply is important during the dive, it does not encompass the primary focus of the buddy check, which is equipment readiness. Enhancing mutual diving skills and assessing dive conditions are also important aspects of diving but fall outside the specific intention and timing of the buddy check procedure.
