Halcyon Symbios Blue Dive Computer

The Halcyon Symbios Blue Handset Dive Computer delivers the same intelligent design, display technology and connected ecosystem as Halcyon's flagship Symbios Silver Handset, but without wireless CCR integration. It gives open-circuit, sidemount, and fixed-setpoint CCR divers access to the Symbios platform at a more affordable price point.

Think of the Halcyon Symbios Blue as the exact same computer as the more expensive flagship model, inside and out, but with one major feature that open-circuit divers do not need removed, making it much more affordable for them at a compelling price point.

It supports oxygen, nitrox, and trimix, includes Fixed Setpoint CCR mode, and connects with the full Symbios ecosystem, including the GPS Pod, DPV, Tank Pod, and other future innovations.

If you are an open-circuit diver (single tank, twinsets, or sidemount), the 120m depth-rated Symbios Blue, with its high-resolution 2.4" transflective full-colour display (320 × 240 px), does everything you need.

Product FAQs

What is the Halcyon Symbios ecosystem?
The Halcyon Symbios ecosystem is a connected range of dive technology built around the Symbios Dive Computer, Symbios Blue Dive Computer, Symbios HUD, Symbios Tank Pod and Halcyon app.

Each component can operate independently or be combined to create a more integrated diving system.

A diver can start with a Symbios handset or HUD as a standalone dive computer, add the Symbios Tank Pod for wireless gas pressure monitoring and real-time trim feedback, and expand the system as their diving requirements evolve. The ecosystem is designed for recreational, advanced, technical, Trimix and CCR divers.
What is the difference between the Halcyon Symbios Blue and Symbios Silver Computer?
The Symbios Blue includes the same core platform, display, app integration, Tank Pod compatibility, Gradient Factor visualisation and open-circuit Trimix capability as the Symbios Dive Computer.

The main difference is that the Blue does not include advanced wireless CCR integration features such as eCCR connection, PO₂ monitoring and CCR system data.
Can the Halcyon Symbios Blue be used without the Tank Pod?
Yes. The Symbios Blue is a fully functional standalone dive computer. Adding a Symbios Tank Pod enables wireless gas pressure monitoring and patented real-time trim feedback.

You can connect up to 9 wireless transmitters or connected devices simultaneously.

In example:
Tank PODs: Wireless tank pressure monitoring
pO2 Transmitters: Support for fixed-setpoint Closed-Circuit Rebreather (CCR) units
DPV/Scooter Telemetry: Data from compatible Diver Propulsion Vehicles
GPS Pods: Surface tracking and positioning
Buddy/Student Screens: Receiving data from other divers' units
Does the Halcyon Symbios Blue support Trimix?
Yes. The Symbios Blue supports multi-gas open circuit Trimix diving using the Bühlmann ZHL16-C algorithm with adjustable gradient factors.
Is the Symbios Blue suitable for CCR diving?
The Symbios Blue supports fixed-setpoint CCR diving but does not provide wireless integrated CCR connectivity. Divers requiring wireless eCCR data, PO₂ monitoring and advanced rebreather integration should choose the Halcyon Symbios Dive Computer.
Does the Symbios Blue work with the Symbios HUD?
Yes. The Symbios Blue is part of the Halcyon Symbios ecosystem and can be used alongside compatible Symbios components, including the HUD and Tank Pod.
