Infinity 40-lb BC System w/ AL backplate, 6 lb (2.7 kg) Convertible STA



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 Halcyon¡¯s 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 Halcyon¡¯s new Deluxe Harness Pads, providing the ultimate in diving comfort and convenience.

The Infinity BC features Halcyon¡¯s immensely popular Eclipse wing. The long, narrow profile supports a diver¡¯s tank along his or her entire length, preventing unnecessary drag and minimizing in-water effort.
