BC 1 User's Manual
30
Before adapting your BC for use with double cylinders, it is important to compare
the buoyancy of your particular BC size and model with the specifications of
the cylinders, the amount of weight you will carry, and the type of exposure suit
you will wear.
Your BC’s backpack or harness 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
Buoyancy and Cylinder
Capabilities section of this manual
prior to attaching double cylinders to
confirm the approved double cylinders for your particular BC.
Your BC can accommodate a twin tank kit. Identify which cylinder band your
BC uses and choose from the following options:
• 427107 GripLock Twin Cylinder Kit.
• 427042 Universal Twin Cylinder Kit.
Double Cylinder Set-up
WARNING
:
When fully charged and worn together as doubles, some
cylinders may create enough negative buoyancy to counteract the
amount of buoyancy 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 backpack or harness. Such an event while diving may separate you
from your primary air source, and could lead to serious injury or death.
