Which item is considered an essential feature on all buoyancy compensators?

• A. Power inflator mechanism
• B. Overpressure relief valve
• C. All of the above
• D. Inflator/deflator hose

Answer: (C)

Diving with a buoyancy compensator relies on having a reliable way to add and remove air from the bladder and a safety mechanism to prevent overinflation. The power inflator mechanism provides the primary means to fill the BC quickly and efficiently. The inflator/deflator hose is the essential conduit that carries that air to the bladder and also allows deflation when needed. The overpressure relief valve acts as a safety vent that automatically releases air if the bladder would otherwise overinflate, protecting you and the gear. Together, these features ensure you can safely adjust buoyancy and stay under control in different depths and situations. That’s why all of the above is the best answer.
