Halcyon Symbios BLUE Handset

The Symbios Blue - Your Entry into the Symbios System

The Symbios Blue Handset Computer brings the core features of the Symbios System into a more accessible and affordable configuration – without compromising on quality, display, or ease of use.

The full-color transflective display remains clearly readable even in direct sunlight without backlight – saving battery life in the process. Large, clearly structured digits allow quick information capture even under load, while a simplified main screen keeps the most critical data front and center. Fields, screens, and functions are fully customizable to your preferences.

The intuitive two-button operation works reliably even with gloves. Supported diving modes include Trimix OC and adjustable Gradient Factors. The integrated Gradient Factor chart visualizes in real time which tissue compartment is driving your decompression. The pressure sensor is chlorine-resistant, making it well suited for frequent pool use in training environments.

Through the Halcyon App (Android & iOS), the Blue can be fully configured before the dive: set up gas tables, adjust settings, customize screen layouts, and simulate dives – including gas switches and response scenarios. After the dive, logbook and data review are available at your fingertips.

Please note: The Symbios Blue does not include the wireless rebreather connectivity and full CCR integration of the Silver model. For CCR divers, we recommend the Symbios Silver.
