TheHalcyon Symbios HUD dive computeris ideal for divers seeking hands-free data monitoring via a sophisticated Head-Up Display. It will meet the requirements of expedition, rebreather, professional and military divers, as well as underwater photographers and videographers.

The Symbios HUD will help any diver concentrate on their dive instead of constantly monitoring a wrist computer, with a lower task load.

When mounted to a mask, this HUD is comfortable and lightweight. Clear information is readily available to CCR and Open-Circuit divers without needing to check a handset.

The Symbios HUD can be used alone, in conjunction with the Symbios Handset or Tank Pod, or as part of a Complete Symbios Set consisting of the Handset, Pod, and HUD. It has very similar functionalities to the handset, and all the screens are familiar, allowing easy access to the same information, but in a nice, small form factor.

You can also purchase the Symbios HUD and Tank Pod Set.

Together with the Symbios Handset, the HUD and handset are the core of Halcyons Symbios Technology, an ecosystem designed to enhance your diving experience with advanced features and prepare you for todays adventures and tomorrows challenges.

The Symbios HUD is a small form factor multi-gas dive computerthat uses theZHL16-C algorithmwith adjustable gradient factors. It can accommodate up tofive gases for Open-Circuit diving, fixed or integrated CCR, Integrated Sidemount, and Gauge modes.

The Symbios HUD is depth-rated to120 metresand operates on a rechargeable Li-ion battery, providing up to12 hours of runtimewithfive brightness levels. Similar to the Symbios handset, the unit also displays the normal maximum average for any dive, CO2 levels, and the CNS and OTO accumulations, along with the gradient factor.

The Symbios HUD’s TFT Full-colour display offers a virtual image of ~ 20x20cm2 at a distance of 70cm with a screen resolution of 240×240.
