Halcyon Symbios™ CCR Pods (Wireless Rebreather Transmitter)

Your CCR Gets Wireless Now. Seamless Integration.

The Halcyon Symbios™ CCR Pods revolutionize your technical diving configuration by connecting compatible closed-circuit rebreathers (CCRs) wirelessly to the Symbios Silver Handset and HUD. This advanced wireless bridge acts as a dedicated transmitter, bringing critical real-time CCR information into the Symbios ecosystem. By eliminating cumbersome physical cables between the rebreather head and your display, this wireless connection supports a significantly cleaner, more streamlined, and integrated equipment setup while ensuring divers have immediate access to essential life-support data on their preferred Symbios displays.

Real-Time Data & Intelligent Power Management

Designed for absolute precision, the Symbios CCR Pod transmits individual cell readings, displaying the exact pO₂ value from each connected oxygen sensor. Utilizing highly reliable wireless magnetic transmission, the pod updates and transmits vital CCR data once every single second to ensure you are never without real-time insights. For optimal efficiency, the analog versions automatically enter sleep mode after more than 15 minutes of stable sensor output, preserving the internal CR123 lithium battery for up to 200 diving hours or one year on standby.
