Halcyon Eclipse™ Buoyancy Control System

The Halcyon Eclipse™ Buoyancy Compensator System is establishing a new standard for single cylinder recreational diving, while creating unprecedented streamlining and eliminating the many unnecessary “features” that clutter traditional buoyancy compensators.

The Halcyon Eclipse™ Buoyancy Compensator System comes standard with a wing, backplate, harness, and crotch strap, harness hardware, single tank adapter with cylinder straps and a MC Storage Pak™. Assembly is required by the user.

Both the Eclipse™ and Adventure/Traveler™ Pro wing have a long, narrow profile that supports the diver’s single tank along his or her entire length, preventing unnecessary drag, and minimizing in-water effort. Meanwhile, the infinitely adjustable harness prevents the frustrating lack of control found with typical buoyancy compensators.

This BC system improves stability and reduces drag by encouraging a streamlined position — these changes result in less effort and more diving fun.
