Halcyon Symbios Blue Handset Computer

Clarity. Adaptability. Progression.

The Halcyon Symbios Blue Handset Computer is built to support your diving across all environments, configurations, and experience levels. Designed as a wireless, ultra-slim, and glove-friendly instrument, it delivers the essential tools you need in a reliable, straightforward system. Whether you are training, traveling, or diving regularly, the Symbios Blue is an evolving platform that grows seamlessly with your underwater ambitions.

Everyday Diving & Unmatched Readability

Engineered for perfect clarity, the Symbios Blue features a 2.4" full-color transflective display that remains highly readable even in the brightest, sunlit conditions without relying on high-drain backlights. This power-efficient screen extends battery life and features a large, easy-to-read layout. The simplified main screen allows for quick data recognition, while additional, highly customizable data fields are organized neatly into secondary pages to match your exact dive preferences.

Train and Simulate: On Land & In Water

Familiarize yourself with your equipment before you even hit the water. Through the powerful Halcyon Bluetooth app, you can drive all functions and simulate complex dives right from your phone—adjusting variables like depth, time, pressure, and O₂ cells. Once in the water, you can safely practice decompression scenarios in shallow environments, ensuring you are fully prepared for the real dive.
