Halcyon Aura Octopus
The Aura secondary regulator, or octopus, is a downstream valve second stage. Its compact and simple design makes it perfect as an octo. You can use the Air Control Vane (ACV) to put the reg into ‘Halcyon’ mode, so it won’t free flow while not in use.
The comfort mouthpiece of the Aura Occy is designed to reduce jaw fatigue. So if you ever have to swap to your secondary regulator, you will still have a comfortable dive.
