What equipment should divers check during a buddy check?

During a buddy check, divers should thoroughly inspect each other's tanks and regulators to ensure they are functioning properly and are ready for the dive. This includes checking that the tanks are full, properly attached, and free from leaks. The regulators should be checked to ensure they are in good working order, providing air as expected.

Ensuring that these vital pieces of equipment are operational is crucial for diver safety. Each diver relies on their gear to provide a reliable air supply during the dive, so verifying the condition of tanks and regulators helps prevent equipment failure underwater, which could lead to dangerous situations.

While other pieces of equipment, such as personal gear, dive lights, weights, and buoyancy devices, are important, the tanks and regulators are critical to life support underwater. Therefore, focusing on these elements is essential during a buddy check to enhance safety and build confidence before entering the water.
