The Halcyon Symbios BLUE Handset Dive Computer delivers the same intelligent design and feature-rich ecosystem as Halcyon's flagship Silver Symbios handset, but without wireless CCR integration, allowing divers to access this cutting-edge platform at an even more compelling price point.
The 120m depth-rated Symbios Blue Handset is well-suited for recreational, technical, and sidemount diving across various environments. It includes a Fixed Setpoint (FSP) CCR mode for non-wireless CCR integration and supports up to 5 gases for OC and CCR diving.
The Blue, described as a streamlined version of Halcyon's flagship Symbios Silver dive computer, is designed for divers who seek reliable performance from a dive computer with tactile buttons, vibration alerts, a 3-axis compass, and Bluetooth connectivity.
The Symbios Blue 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.
The Blue's Dive Modes are identical to those of the Silver:
- Open Circuit

- Gauge
- Buddy Screen
