Halcyon Symbios HUD Computer

Halcyon Symbios HUD - All Your Data. Always in Sight.

The Symbios HUD is the smallest and lightest full-feature HUD dive computer in the industry – and at the same time a fully autonomous dive computer mounted directly on your mask frame. No separate console, no distraction. All critical information is exactly where you are looking.

The high-resolution full-color display projects a virtual image of approximately 30 × 30 cm at a viewing distance of one meter – clear, stable, and readable at a glance, even under high task loading. Your hands stay free, your focus stays on the dive.

Like all Symbios devices, the HUD is part of the connected Symbios ecosystem. It receives wireless data from the Symbios Tank Pod – enabling real-time pressure transmission and the patented Trim Indicator, which brings your body position feedback directly into your line of sight. The Buddy Screen displays your dive partner's pO₂ values and tank pressures – particularly valuable for instructors monitoring multiple students at once. Compatible wired CCR systems can be integrated wirelessly into the HUD, with real-time pO₂ data included. An intuitive color-coding system makes pO₂ status instantly and unmistakably clear.

The Gradient Factor chart delivers real-time insight into your decompression; supported modes include Trimix OC, CCR, and adjustable Gradient Factors. Through the Halcyon App, the HUD can be fully configured before the dive – gas tables, settings, simulation – and after the dive, logbook and data review are available at your fingertips.

The Symbios HUD is the first choice for underwater photographers, researchers, public safety divers, and anyone diving under high task loading who cannot afford to lose control for a single moment.
