VALVE SYSTEM
OVER PRESSURE VALVE OPERATION
Over Pressure Valves prevent over-inflation of the BC. If the internal pressure exceeds the
spring pressure in one of the Over Pressure Valves, the valve automatically opens and re-
leases air to prevent damage to the BC. The Valve will automatically close when the internal
pressure drops back below the spring pressure.
The total weight a diver requires to descend from the surface and achieve neutral buoyancy
depends on various factors, each of which should be taken into consideration when
determining the ideal amount of ballast;
a. Diver’s inherent buoyancy.
b. Exposure suit thickness and inherent buoyancy.
c. Cylinder type (steel versus aluminium), size and buoyancy characteristics.
d. Water salinity.
Your SCUBAPRO HYDROS PRO is fitted with two available weight carrying systems. Once you
know what your total weight requirement for a specific dive will be, you can elect
whether to use none, one or both of the available systems:

BUCKLE WEIGHT SYSTEM
Accommodates 2 X 4.5kg / 10lbs in pockets that fit into the Weight Holsters of the HYDROS
PRO. The pockets are secured with mechanical quick-release buckles and can be ditched
easily when exiting the water or in emergencies.
TO LOAD THE BUCKLE WEIGHT SYSTEM:
a. Insert the desired amount of weight into the zippered Weight Pockets and completely
close the zippers.
b. Distribute the weight evenly between left and right pockets to promote even trim
underwater.
c. It is advisable to use soft weights such as SCUBAPRO Eco Weights as they reduce wear
of the BC pockets and are more comfortable. The sealed SCUBAPRO Eco Weights have
the added environmental benefit of preventing lead contact with the water.
d. Slide the loaded Weight Pockets into the Weight Holster, ensuring it is pushed in all the
way to the back of the holster.
e. Snap-fit the female buckle on the Weight Pocket onto the red male buckle on the Weight
Holster.
f. Gently take up the slack in the webbing by pulling on the plastic D-ring. It is not necessary
to overtighten the webbing.
Note: Many divers find it easier to don the BC first, and then load the weight Pockets into the
BC so that they never have to handle the fully-weighted BC.
