Attaching Your Tank to the BCD
  1. If the cylinder is equipped with a yoke valve, inspect the valve's o-ring for signs of wear or cracks. Replace the o-ring if it's defective or missing.
  2. Stand the cylinder in an upright position with the valve knob positioned to your right side.
  3. The tank strap will stretch when wet, so soak the strap in water to prevent it from loosening during the dive.
  4. Lower the BCD's tank strap over the cylinder, and rotate the cylinder until the valve knob points to the BCD's right side.
  5. Make sure the strap is correctly woven through the buckle, and close the buckle. Tighten the strap if it's loose.
  6. Pick up the BCD by its handle or shoulder straps and make sure the cylinder is securely fastened and does not slip.
