Non-Releasable Weight
To supplement the releasable weight, some BC’s are designed to carry non-releasable weight in two
fixed pocket locations.
To install weight into the non-releasable weight pockets, simply disconnect the flap buckle, slide in the
block weight, fold the flap over the pocket, and reconnect the buckle. Weight should be added to the
non-release (trim) pockets after the BC has been secured to the cylinder.
The non-releasable weight pockets are designed to hold single rectangular block weights. To avoid
accidental loss of weight, Apeks strongly advises against using small bullet-shaped weights and shot
weight.
Refer to the Weight Capacity Charts for maximum non-releasable (trim) weight capacity.
Because the weight is non-releasable, it must not be used as your primary source of ballast. After
filling the fixed pockets with weight, it is extremely 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 addition 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.
