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
BC Buoyancy
and Cylinder Capabilities section of this manual
prior to attaching double cylinders to confirm the
approved double cylinders for your particular BC.
Select BC’s can accommodate an Apeks Twin Tank Kit. Consult your local Apeks Dealer or Distributor
for more information. Dealer or Distributor and product information can be found on the Apeks website

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 twin 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.
