The Halcyon Pro Doubles BC System is a twinset backplate and wing BCD that combines the Halcyon Evolve wing in 40 lb (18 kg) or 60 lb (27 kg) lift with a carbon fiber backplate and integrated Cinch quick-adjust harness. The Halcyon Legend MK2 wing can be configured for improved trim and hose routing. The carbon fiber plate is lightweight and corrosion-resistant, and the harness is available in standard or small sizes with deluxe shoulder and backplate padding, making the system suited to expedition diving, technical instruction, and traveling technical divers.
Hardware can be configured in stainless steel or lightweight aluminum, and the standard configuration includes the MC storage pack. Each system is built to order through the Halcyon Go Custom program, which supports wing color selection across the full Halcyon fabric palette, logo color choices, optional custom embroidery, ACB integrated weight pockets, and trim weight pockets. Every configured system ships with an inflator with a 52 cm / 22 in LP hose, assembled and packed in a Halcyon Traverse bag.
