will require the use of a corded light. In this case, divers may wish to use the included D-rings to attach a primary
light as in figure 9. A bungee loop can be added for additional security. Optional mounting straps can be purchased
which allow an argon bottle or primary light to be fitted to the bottom of the Contour
™
(figure 10).
CAUTION: It is important not to overweight the diving rig with too much fixed weight; this
configuration may not allow sufficient removable weight, preventing the diver from “ditching”
the weight and swimming to the surface during an emergency.
CAUTION: You should be certain, through in-water testing prior to a dive, that without any air in
your buoyancy compensator you are capable of swimming against the weight of your
configuration with full tanks and all weight in place. You need to verify that you are able to
manage your scuba configuration in the event of a buoyancy compensator failure.
PRE-DIVE BC SYSTEM INSPECTION
Before each use, the BC must be given a thorough visual inspection and functional test. Never dive with a BC
that shows signs of damage until it has received a complete inspection and service from an Authorized Halcyon
Dealer. Periodically, it is advised to check the buoyancy compensator OPV for damage or corrosion and the harness
webbing for signs of wear. If your harness shows significant wear, replace the webbing before diving.
Inspection Checklist
1. Connect the wing’s power inflator to a clean air source via the LP quick-disconnect hose. Depress and release the
inflator button intermittently to ensure that the airflow is unobstructed, and that the airflow stops completely
when the button is released.
2. Manually operate the overpressure (OP) valve by pulling on the attached string to test spring and valve integrity.
Fully inflate the buoyancy wing until the OP valve opens. Regular inspection of the OP valve for corrosion or
damage is recommended.
3. Examine the operation of the OP valve by repeatedly inflating the wing to ensure that the valve opens to relieve
excess pressure, yet closes immediately afterward to allow the bladder to remain taut and fully inflated.
4. Check the function of the oral inflator button, rapid-exhaust valve, and overpressure/manual dump valve to
ensure a rapid and unobstructed exhaust from each valve. Listen closely for any leakage with the wing fully
inflated but not connected to a low-pressure air source. If there is any suspicion of leak, submerge and —once
equalized to depth — check for continued bubbling.
5. Check that all weight is secure and verify that pockets are in proper position.
6. Make a final check of tension of bungee straps holding your SCUBA cylinders to ensure that they have not
loosened due to stretching. Ensure there is no damage on these straps.
