Once in the water, agree on the surface procedures with your divebuddy.Even while still on the surface, the buoyancy advantages of theHUB will already become apparent: in fact the distribution of the airmasses helps maintain the diver in a vertical position. WARNINGThe rear pockets are sized to accommodate a maximumof 1.5 kg (3.3 lbs.) of weights each.Refer to your instructor for information about how tomake the most of this feature.USING THE HUB UNDERWATERTo begin the descent, there is no need to raise your left arm aswith traditional BCs: simply press the "OUT" button on the inflatorunit, or operate one of the mechanical quick air dump valves bypulling its cord.During the descent, compensate for the progressive loss ofbuoyancy by pressing the "IN" button with your thumb to inflate theBC.USING THE REGULATORTake the regulator out of the right pocket and put it in your mouth.Pull a sufficient length of hose out of the pocket to permitcomfortable use of the regulator.The hose can be fixed in the desired position using the two slidersof the pocket zip.During the dive, it is possible to vary the length of free hose bypulling out the hose or pushing it back into the pocket. WARNINGFor correct use of the regulator, the hose must bepositioned, into the pocket, as shown in the figure 8.USING THE PRESSURE GAUGE OR CONSOLEOpen the left pocket.Pull out the instrument in order to monitor it.Also in this case, it can be fixed in the desired position using thetwo sliders of the pocket zip.DURING THE ASCENTTo control the speed of ascent, it is necessary to discharge someof the excess air.Use the OUT button, pressing it briefly and repeatedly.In the event of an excessively rapid ascent, a quick air dump canbe made by holding down the OUT button.- 9 WARNINGDuring the ascent, the buoyancy must be adjusted toprevent an excessive rate of ascent near the surface.Consult your instructor or dive manual for moreinformation about a safe rate of ascent. Follow theindications of your dive table throughout the entireascent phase. WARNINGWhen ascending, your buoyancy must be controlled toavoid too rapid an ascent when approaching thesurface. For information concerning a safe rate ofascent, refer to a certified diving instructor or yourdiving manual. Follow your decompression table ordive computer during the whole ascent. Failure to makea slow, controlled ascent with a safety stop could leadto serious injury or death.USING THE ALTERNATIVE SECOND STAGEOpen the alternative second stage pocket by pulling the yellowknob.Take out the alternative second stage in order to use it.The alternative second stage can be temporarily replaced bypassing the hose inside the special compartment, as shown inphoto 9.- 8 WARNINGDo not use your B/C to lift objects in the water. Shouldyou drop the object, you could become too buoyant andyour rate of ascent could become too rapid andpotentially dangerous. Serious injury or death couldresult.14
