The Halcyon Symbios BLUE Computer is a compact, adaptable dive computer designed to deliver clear information and intuitive operation across recreational, technical and rebreather diving. Its ultra-slim, rugged design features a 2.4" full-colour transflective display, providing excellent readability in bright conditions while remaining power efficient.
Powered by the Bühlmann ZHL-16C algorithm with adjustable gradient factors, Symbios BLUE supports oxygen, nitrox and trimix, along with open circuit and fixed-setpoint CCR diving. Customisable screens allow you to prioritise the information that matters most, while vibration alerts, a digital compass and tactile two-button controls make operation straightforward even when wearing gloves.
Bluetooth connectivity with the Halcyon app allows you to configure settings, simulate dives and familiarise yourself with the computer before entering the water. Compatibility with the wider Symbios ecosystem, including tank pods, also allows the system to expand as your diving progresses.
