Compatibility & Options
Choose your bladder configuration from the dropdown.
Single Bladder
The standard version with one buoyancy bladder.
Dual Bladder
Adds an independent backup bladder for divers whose equipment configuration and dive plan require redundant buoyancy. This provides an alternative buoyancy source rather than doubling the system’s stated lift.
The harness can be configured in H or Y arrangements. Additional components may be required when changing the supplied configuration.
Cylinder rigging, weighting and harness adjustment should suit your equipment and sidemount training.
