Symbios™ CCR Pods
Your CCR gets wireless now. Halcyon CCR Pods connect compatible rebreathers wirelessly to the Symbios Silver Handset and HUD, bringing CCR information into the Symbios ecosystem.
The wireless connection supports a cleaner, more integrated equipment setup while allowing divers to access essential CCR information on their preferred Symbios display.
Your CCR gets wireless now
CCR Pods are available with Fischer, 4-pin, and 5-pin connections, including male and female options for different rebreather configurations. Choose the connector designed for your CCR and pair the Pod with a Symbios Silver Handset, HUD, or both. This configuration-based approach extends the Symbios ecosystem's flexibility to a wider range of closed-circuit rebreathers.
