The final preparation before beginning the dive is the pre-dive buddy check. The buddy check provides an opportunity to identify any gear problems while still at the beach or boat deck where corrections can easily be made.

Divers learn various buddy check methods, so your buddy may check your equipment differently than how your instructor taught you. But regardless of the specific system used, make sure the following is verified:

• Valve knob is opened, and cylinder is full.
• 2nd stage and octopus operate correctly.
• The power inflator operates correctly.
• Weight belt is donned to allow release with the right hand, and the BCD does not interfere with the ability to ditch the belt.
• All straps and clips are fastened.
• Your buddy has not forgotten a mask, fins, or any other equipment required for the dive.
