Experience exceptionally smooth and natural breathing with the Halcyon Halo Second Stage Regulator. Engineered for steadfast reliability and impeccable performance, the Halo features a balanced, downstream valve that delivers a high volume of air with minimal effort, regardless of depth or cylinder pressure. Divers can fine-tune their breathing experience using the easily accessible inhalation control knob, tailoring the air delivery to their preference. Additionally, the Air Control Vane (ACV) allows for further adjustment, providing powerful vacuum-assisted breathing in the "dive" position and helping to prevent freeflows when on the surface, scootering, or when used as a backup (in "Halcyon" position). Compatible with up to 40% Nitrox, the Halo is a top choice for demanding divers, including technical, cave, wreck, and CCR enthusiasts. It pairs perfectly with Halcyon's H-75P or H-50D first stages and comes standard with a comfort mouthpiece designed to reduce jaw fatigue, enhancing overall dive enjoyment and focus.
