Which statement best describes the pre-dive ABC check acronym?

• A. Air On, BC Inflated, Computer Checked And Activated
• B. Air On, BC Inflated, Computer Checked
• C. Air On, BC Inflated, Computer Activated
• D. Air Inflated, BC On, Computer Checked

Answer: (A)

The pre-dive ABC check focuses on three critical readiness steps: the air supply, the buoyancy control device, and the dive computer. Air On means the tank valve is open and the regulator is delivering air, confirming you have a breathable gas supply and that the regulator is functioning before you enter the water. BC Inflated ensures the buoyancy system can provide lift when needed and lets you verify you can control buoyancy on entry, descent, and ascent. Computer Checked And Activated means the dive computer is functioning, set to the correct gas, and then activated so it starts monitoring depth, time, and no-decompression limits during the dive. This combination ensures you’re physically ready to dive, can manage buoyancy, and have the computer actively guiding you. Other options miss either the activation step, use incorrect BC terminology, or imply an incorrect action for the air or computer, making them less accurate representations of the standard pre-dive check.
