What is an important factor to check during a buddy check?

One of the key aspects of ensuring a safe dive experience during a buddy check is confirming that both divers understand the emergency signals. This understanding is essential because communication underwater can be challenging, and clear signals can mean the difference between managing a situation effectively or facing difficulties. Knowing how to signal for help or communicate other important messages enhances safety and coordination between buddies, allowing them to respond appropriately in case of an emergency.

While factors like air consumption rates, equipment malfunction history, and compatibility of dive computers are certainly relevant to diving safety, they do not have the immediate impact that emergency signal understanding does during a pre-dive safety check. Signals must be established and understood before entering the water, ensuring that both divers can react promptly and effectively in any situation that may arise.
