Core Symbios handset
Keep the colour display, decompression tools and app-supported setup without paying for wireless CCR capability.
Halcyon
The Halcyon Symbios Blue Handset brings the core Symbios experience to divers who do not need live wireless rebreather data. Its colour transflective display, mixed-gas decompression, sidemount mode, Tank Pod support and app connection cover a broad path from regular recreational diving into more involved open-circuit configurations.
Blue also includes fixed-setpoint CCR mode, but that boundary matters: it cannot receive wireless CCR or CCR Pod information and cannot be upgraded to do so. For an open-circuit or sidemount diver, that distinction keeps the choice straightforward. For a diver planning connected CCR use, Silver is the appropriate handset to assess.
Keep the colour display, decompression tools and app-supported setup without paying for wireless CCR capability.
Add compatible wireless cylinder pressure and trim information for open-circuit or sidemount diving.
Configure up to five gases and use a dedicated two-cylinder sidemount workflow.
Use planned setpoints without implying live wireless CCR or oxygen-sensor integration.
