BCD’s that have an integrated weight system come with the weight pockets. The weights themselves are not included. BCD’s which have optional weight pockets are not included, however, can be purchased. BCD’s which do not have an integrated weight system can only be used with a weightbelt.
The INT (or yoke) connection uses a clamp type to mount the regulator over the cylinder valve and is tightened into place by screwing the cap. This pushes the first stage into the sealing o-ring of the cylinder valve. With the DIN fitting the male part is screwed into the valve to securely capture the o-ring. We recommend the DIN connection, since this is safer. This connection is mostly used for 300bar cylinders. However, the DIN300 bar connection also works with a 200bar tank valve
