SPECIAL FEATURES - Double Cylinder Setup - Using Apeks Twin Tank Kit
The Black Ice Twin Tank Kit (P/N 427106) allows mounting of twin cylinders to your BC in all sizes.
Please see mounting instructions provided with the kit.
Before adapting your BC for use with double 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 may also have certain weight limitations depending on the size and model, as double cylinders
vary in both size and weight. To ensure your safety, refer to the tag located on the inside BC pocket prior
to attaching double cylinders to confirm the approved double cylinders for your particular BC.
WARNING: When fully charged and worn together as doubles, 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 double cylinders
may also lead to structural failure of the wrapture harness. Such an event while diving may
separate you from your primary air source, and could lead to serious injury or death.
