Course Outline

Objective: Assemble your equipment, ensuring that all components are safely attached and that all safe diving protocols are followed.

Value: Correct assembly of your equipment will ensure that your equipment is safe for you to dive.

How It’s Done:

  1. Tighten the buoyancy control device (BCD) cylinder straps, and position them correctly on the cylinder.
  2. Secure the regulator’s first stage to the cylinder pillar valve facing the BCD.
  3. Ensure that the primary second stage and alternate air source (AAS) are routed over the right BCD shoulder strap.
  4. Attach the low-pressure inflator (LPI) hose to BCD inflator.
  5. Check that the SPG is registering zero pressure.
  6. Slowly open the cylinder valve and allow the pressure to build up before fully opening the cylinder valve. Note what the cylinder pressure is.
  7. Breathe from the primary second stage, and watch the needle on the SPG to ensure it does not move.
    • If it does move, either the cylinder valve is not completely open or there is a fault with the SPG.
    • Remember that the regulator delivers air at ambient pressure so it should feel like normal breathing.
  8. Breathe from the AAS, and watch the SPG.
  9. Inflate the BCD completely. Ensure the dump valves are working and the BCD holds full inflation.
  10. Ensure the weight system with quick release is unobstructed. Ensure the weight belt is set for a right-hand release.
  11. Secure the AAS, the SPG, and any other items. Ensure there are no dangling items.
  12. Turn on the personal dive computer (PDC), and perform a battery check.
  13. Ensure the PDC is set to standard air mode.
