BD BUOYANCY COMPENSATOR USER'S MANUAL
The Twin Tank Kit (PN 427042) allows mounting of twin cylinders to your BC.
Please see mounting instructions provided with the kit.
Before adapting your BC for use with twin cylinders, it is important to compare
the lift capacity of your particular BC size and model with the buoyancy
specifications of the cylinders, the amount of weight you will carry, and the
type of exposure suit you will wear.
Your BC’s backpack may also have certain weight limitations, as twin
cylinders vary in both size and weight. To ensure your safety, refer to the tag
located on the inside BC pocket prior to attaching twin cylinders to confirm
the approved twin cylinders for your particular backpack.
Double Cylinder Setup - Using Aqua Lung twin tank kit
WArNiNg: When fully charged and worn together as twins, some
cylinders may create enough negative buoyancy to counteract the
amount of lift your BC can provide. At depth, this can lead to a
dangerous situation if your wetsuit becomes compressed and you
can no longer achieve positive buoyancy by jettisoning weight. the
excess weight of some twin cylinders may also lead to structural
failure of the backpack. Such an event while diving may separate
you from your primary air source, and could lead to serious injury
or death.
