The Complete Halcyon Symbios Dive System
Dive smarter, safer, and with total awareness. The Halcyon Symbios BLUE Handset, HUD & Tank Pod Bundle brings together three purpose-built components from the Halcyon Symbios ecosystem into one complete, seamlessly integrated dive computer system.
From real-time wireless tank pressure to hands-free heads-up display data, this bundle equips recreational divers, technical divers, instructors, and underwater photographers with everything they need to stay informed, streamlined, and in control — dive after dive.

With its full-colour TFT micro-display producing a virtual image of approximately 20 × 20 cm at 70 cm distance, data is clear and immediately readable.

3. Halcyon Symbios Tank Pod
The Halcyon Symbios Tank Pod is a smart wireless hub that does far more than transmit tank pressure. Compatible with any first stage, it delivers real-time gas data wirelessly to your Symbios dive computer — eliminating high-pressure hoses for a cleaner, more streamlined rig.
When paired with the Symbios system, the Tank Pod also shares nearby buddy tank pressures and provides exclusive patented trim analysis , giving you precise real-time feedback on your underwater positioning. If you don't need the trim feature, simply rotate the battery and the Tank Pod switches to pressure-only transmission — putting you in full control of your setup.
Key Features:
Accurate wireless tank pressure transmission
Patented trim position analysis for precise diver positioning
Buddy tank pressure sharing within the Symbios ecosystem
Compatible with any first stage
Cleaned for oxygen service
Visual and vibratory low tank pressure alarms
