Halcyon is opening exclusive instructor pricing on the full Symbios range — the HUD, the Silver and Blue handsets, and the patented Tank Pod. Confirm your teaching credentials to unlock your pricing.




Your dive data, right where your eyes already are.
The smallest and lightest HUD ever built — mask-mounted, fully autonomous, and impossible to ignore. Critical information floats in your natural line of sight, so you never look down, never break focus, and never lose your team. Open circuit or CCR, the HUD keeps you ahead of the dive.


The flagship handset for divers who run the whole system.
Wireless, ultra-slim and glove-friendly, with a full-color transflective display that stays razor-sharp in direct sunlight — no backlight needed. Silver is built for advanced open-circuit and rebreather diving, tracking your dive, your team and your decompression in real time as setups get more serious.


The computer that grows with every diver you certify.
Wireless, ultra-slim and glove-friendly, Blue makes advanced capability approachable. A power-efficient transflective color display, a simple two-button interface and a rugged, compact body make it the ideal first serious computer — and it scales from open circuit all the way to fixed-setpoint CCR.
