About

The Halcyon Symbios Blue is a clear, easy-to-use dive computer that grows with your diving. It is wireless, slim and easy to use with gloves, and its 2.4" full-colour transflective screen stays readable even in bright sunlight.

The main screen keeps things simple, with more data on extra pages and display fields you can customise. A Gradient Factor chart shows your decompression and the leading tissue in real time, and with a Symbios tank pod you also get tank pressure and trim monitoring. With the Halcyon app you can set up gases, screens and profiles on your phone, and simulate dives on land or in shallow water to learn every function before a real dive.

It supports oxygen, nitrox and trimix, open circuit and fixed setpoint CCR modes, uses the Bühlmann ZHL-16C algorithm with adjustable gradient factors and runs for up to 30 hours per charge.
