Pre Dive Checks
WARNING:
Do not use your RB Wing as an assist or “lift bag” for bringing
objects to the surface. These objects may be lost during the
ascent, creating a sudden increase in buoyancy and loss of
buoyancy control.
Do not inhale gases from inside bladder.
Keep sand and other contaminations out of the oral inflation
mouthpiece and valve button. Under certain conditions
contamination can cause the valve to not close completely. If this
occurs while diving, shake the valve while operating it several
times. If the valve leaks or remains inoperable immediately
terminate the dive. Diving with a leaking RB Wing or with valves
that do not operate properly may result in loss of buoyancy control
that could result in serious injury or even death.
•
Check that your RB Wing is free from visible damages, such as e.g. cuts, punctures,
frayed seams, excessive abrasion, and loose/missing hardware.
•
Open your cylinder valve.
•
Check the correct operation of the inflator mechanism by pressing the inflation button
to inflate the bladder, check for leakages, and then shortly press the deflation button.
•
Check the manual deflation device mechanism by pulling the inflator corrugated hose.
(does not apply to models with elbow connection to the bladder)
•
Check that you can reach both APRV:s on the right and left side respectively.
Pull the knob and make sure the correct operation of the APRV.
•
Check that you can reach the handles of your QR weight system to release your own
weights.
•
If a crotch strap is used, check that it is locked and that is does not prevent the
release of weights.
•
Inflate the bladder sufficiently to keep you floating directly after entering the water.
Donning
If a wing is used with the harness, connect the quick connector of the inflator feed hose
to the inflator mechanism.
Ensure you have adjusted the RB Wing size to fit perfectly (see section size adjustment).
Undo waistbelt buckle, crotchstrap buckle and one shoulderstrap buckle. Hang the RB Wing
on your one shoulder, preferably on the side where you have no instruments on your wrist, or
APRV:s on your drysuit. Lean forward and the pre-curved waistbelt will grab around your hips.
Then tighten the waistbelt, until you feel that you comfortably can carry the load with your
waistbelt/lumbar support only.
Finally, tighten the other shoulderstrap and adjust.
Put your weights into your weight pockets and lock the buckle.
Buoyancy control / Adjusting the amount of ballast weight.
Ensuring the wing has sufficient lift capacity and that the amountof ballast weight is correctly
chosen shall be performed in confined water. Consult your SCUBA instructor for additional help
in setting up your equipment and weight.
Wing capacity
With all your standard equipment put on and cylinders at maximum filled, make sure the RB
Wing can keep you floating so that you can hold your air-ways well above the surface.
Ballast weights
With all your standard equipment put on and cylinders close to empty (10-20 bar), dump all gas
from the RB Wing bladder. If you cannot submerge, add 1 kg at the time to your ballast weights
and repeat the test procedure. If submerging takes place before the bladder is completely emp-
tied, you may remove ballast weight instead.
Buoyancy calculation
All different RB Wings are constructed for different purposes, to enable certain kinds of diving,
and to ensure a maximum level of safety. The lift capacity must ensure that at least 3 kg of posi-
tive buoyancy is achieved when inflated, even if releasing ballast weights is forgotten.
