Breathing underwater should feel natural and that experience is one of the things that most clearly separate Halcyon second stages competitors. As soon as you experience the smooth, high volume of air delivered by a Halcyon second stage you will be hooked. The high quality 2nd stage regulators provide diver adjustable controls for the ultimate in breathing performance. Halcyon’s Halo second stage offers steadfast reliability and impeccable performance; two methods of breathing adjustment make it the top choice for demanding Halcyon divers.

The Halo provides amazingly smooth performance in all conditions providing unsurpassed performance with enhanced technology. Balanced, downstream valve offers incredibly smooth breathing in all conditions. The design slightly offsets the force of the downstream air entering from the first stage, allowing reduced spring tension and a decreased inhalation resistance. Halcyon 1st stages are balanced, so the Halo is a perfect fit with either the Halcyon H-75P or Halcyon H-50D 1st stage. Adjustable inhalation control refines breathing effort by way of an easy access control knob; this allows the demanding diver an opportunity to fine-tune the air delivery of the second stage. Air Control Vane (ACV) offers a second diver adjustment for the ability to fine-tune breathing. The ACV uses vacuum assist technology to reduce work of breathing and increase diver comfort. This level of refinement is available on all Halcyon second stages. ACV in “dive” position gives powerful breathing support while ACV in “Halcyon” position helps prevent free flows; this can be helpful on the surface, when diving in currents, while scootering, or when the Halo is used as a backup regulator. Comfort mouthpiece is standard on every second stage to reduce jaw fatigue and mouth irritation. This long lasting mouthpiece requires only a minimum effort to hold comfortably in place. In combination with the freedom of head movement provided by Halcyon’s primary long hose, you will enjoy dives free from the jaw fatigue common with certain mouthpieces and/or poorly balanced hose routing.
