Single Tank BC Systems

Halcyon buoyancy compensators enjoy overwhelming popularity among recreational divers worldwide. We continue to redefine what it means to dive a backplate and harness with two styles of single tank systems. Our new patent pending Infinity BC joins the classic Eclipse BC, further expanding upon Halcyon's cutting edge line of high performance systems. The popular Eclipse BC is a classic backplate and harness design, featuring our uniquely streamlined circular air-cell design. Meanwhile the revolutionary Infinity System represents a substantial advancement in BC design. The patent pending Cinch Quick-adjust harness is an industry-first innovation, blending the performance of a backplate with the convenience and flexibility of a recreational jacket BC. The Infinity also features plush harness padding for the shoulders and the backplate, providing the ultimate single tank diving experience.
