The Halcyon Infinity is not your typical buoyancy compensator. In fact, it establishes a new standard in single-tank diving, offering the unparalleled performance of a back mounted harness and the easy adjustability of a jacket BC. The heart of the Infinity BC is Halcyons Cinch Quick-adjust harness (patent pending). The Cinch harness is also available for double tanks and as an upgrade to existing Halcyon diving systems. The Cinch Quick-adjust provides rapid adjustment of the diving harness, allowing an unprecedented fit and easy equipment removal. The Infinity also features Halcyons new deluxe Harness Pads, providing the ultimate in diving comfort and convenience. The Infinity BC features Halcyons immensely popular Eclipse wing; the long, narrow profile supports a divers tank along his or her entire length, preventing unnecessary drag and minimizing in-water effort. -Cinch Quick-adjust; infinitely adjustable with a simple push or pull of the webbing -Eclipse Buoyancy Compensator (
