Designed for Advanced Diving.
The Halcyon Symbios 'Silver' Handset is built for dives that involve more equipment, more data, and more decisions. As a central communication hub for your diving ecosystem, it supports both open circuit and closed-circuit rebreather (CCR) diving. Whether navigating complex wrecks or deep cave systems, it helps you track your dive, your team, and your decompression in real time, even as conditions and setups become more demanding.
Unmatched Readability & Ecosystem Connectivity
Engineered for clarity in any environment, the wireless, ultra-slim handset features a 2.4" full-color transflective display that remains highly readable even in direct sunlight without the need for a backlight. Beyond just monitoring your own data, the Symbios Silver connects wirelessly to tank pods, supported rebreathers, and an expanding ecosystem. It even offers a dedicated buddy screen to display your dive partner's critical data like PO₂ and tank pressure, enhancing team connectivity and overall safety.
CCR Ready & Decompression Insight
For rebreather divers, the Symbios delivers seamless integration via wireless CCR pods, simplified PO₂ displays, and dual Time-to-Surface (TTS) calculations for both CCR and bailout modes. A single-action bailout control significantly reduces task loading during emergencies. The innovative Gradient Factor chart visually displays leading tissue compartments, providing real-time insights into how your decompression is evolving.
