Non-Releasable Weight
To supplement the releasable weight, the Black Diamond is designed to
carry non-releaseable weight in two fixed pockets located on each side
of the BC, between the harness and air bladder. Each pocket can hold
up to 5 lbs/2.3 kg (10 lbs/4.6 kg total).
To install weight into the non-releasable weight pockets, disconnect the
flap buckle and open the hook & loop flap (Fig. 14). Slide in the weight
block, resecure the hook & loop flap, fold the flap over the pocket, and
reconnect the buckle (Fig. 15).
The non-releasable weight pockets are designed to hold single rectan-
gular weight blocks. Aqua Lung/SeaQuest strongly advises against using
small bullet-shaped weights and shot weight.
Because the weight is non-releasable, it must not be used as your pri-
mary source of ballast. After filling the fixed pockets with weight, it is ex-
tremely important to check your buoyancy in the water while wearing the
BC attached to a fully charged cylinder and your exposure suit. While
standing in chest-deep water, deflate the BC completely and check to
ensure that you can easily achieve positive buoyancy by jettisoning your
releasable weight.
WARNING: The non-releasable weight pockets are intended
strictly for containing non-releasable weight, used in ad-
dition to releasable weight. Do not fill either pocket with
weight unless you are certain you can achieve positive
buoyancy at depth by releasing your weight pouches or
weight belt while your BC is completely deflated.
