What is the key technique for venting a buoyancy compensator at the surface or underwater?

• A. Lean forward.
• B. Use the remote exhaust valve on BC's large-diameter inflation/deflation hose.
• C. Turn your body so the exhaust valve is the highest point.
• D. All of the above.

Answer: (C)

Venting from a buoyancy compensator is most reliable when the exhaust valve is the highest point on your gear. Air inside the BC is buoyant and will rise, so by turning your body so the exhaust valve sits at the top, you provide a clear upward path for that air to escape. This works whether you’re at the surface or underwater, giving you predictable buoyancy control. Using the remote exhaust valve on the hose can help if it’s easy to reach, but it won’t guarantee venting unless the valve itself is the highest point. Keeping the exhaust valve up is the key for effective venting.
