To successfully maintain neutral buoyancy underwater, which statement is correct?

To successfully maintain neutral buoyancy underwater, which statement is correct?

• A. Add or remove air only in large bursts.
• B. Before you can achieve neutral buoyancy, you must first assume a fin-pivot position on the bottom.
• C. Be aware of depth changes and anticipate adding or venting air with the inflator in hand.
• D. None of the above.

Answer: (C)

Maintaining neutral buoyancy comes from balancing the gas in your buoyancy compensator with your body's weight and the surrounding water, and doing so as conditions change. As you move up or down, water pressure changes the buoyancy of the air in your BC and even your lungs, so you need to anticipate how much air to add or vent to stay at the same depth. The inflator lets you make small, precise adjustments to hold a steady position, rather than reacting after you’ve drifted. Large bursts of air can overshoot in either direction, making your depth control unpredictable and unsafe. The idea of needing to sit on the bottom in a fin-pivot position isn’t required to achieve neutral buoyancy; neutral buoyancy is about balance and continuous, controlled adjustments, not resting on the bottom. Therefore, being aware of depth changes and proactively adjusting with the inflator is the best approach.
