Halcyon Symbios™ Handset Computer – Wireless Tech & CCR

The Halcyon Symbios™ Handset is not just a dive computer; it is a complete data hub for your underwater exploration. Designed to be the thinnest, most streamlined tech computer on the market, it eliminates the bulk of traditional handsets while offering industry-leading connectivity.

Crystal Clear Visibility Most color screens wash out in shallow water. The Symbios uses a Hybrid Transflective Display which actually uses sunlight to brighten the screen, making it perfectly readable during bright deco stops or surface intervals, while the backlight ensures clarity in the darkest caves.

Future-Proof Connectivity Symbios is built for the modern diver. It supports Wireless Air Integration for up to 9 independent cylinders (perfect for sidemount and stage bottles) and is ready to receive data from future Halcyon ecosystem devices like DPVs and positioning systems.
