How often should a diver perform a buddy check before a dive?

A buddy check should be performed before every dive as it enhances safety and ensures that both divers are properly equipped and ready for the dive. This practice allows divers to verify each other's gear, air supply, and emergency equipment before entering the water. By conducting a thorough buddy check each time, divers can minimize the risk of equipment failures or oversights that could jeopardize their safety underwater. Regular checks help reinforce communication between partners and build trust, which is vital for effective teamwork during dives. Making this a standard practice regardless of the dive type or frequency helps to establish consistent safety measures among all divers.
