In learning buoyancy control, which option describes how to use air adjustments?

• 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 the need to add or vent air by keeping a hand on the inflator.
• D. None of the above.

Answer: (C)

Managing buoyancy through air adjustments means actively watching how depth changes as you move and using the inflator to make small, proactive changes. The best way is to anticipate when you’ll need more air or venting and keep a hand on the inflator so you can add or release air in fine increments. This lets you maintain neutral buoyancy smoothly as you descend, hover, or ascend, without overshooting. Avoid relying on large bursts of air; big changes can cause overshoot and instability. The idea that you must assume a specific fin-pivot position on the bottom isn’t related to how you manage buoyancy with air adjustments, so it doesn’t address the skill at hand.
