MORE THAN A DIVE COMPUTER

Designed to Support Better Diving

Built to Connect. Designed to Evolve. Symbios unites previously disconnected devices through one integrated wireless ecosystem. Dive buddies, Tank Pods, navigation buoys, lights, DPVs, CCRs, and more—all wireless, all connected, and all accessible through your Handset or HUD. And Symbios doesn’t stop with Halcyon products. The ecosystem extends to Symbios-enabled products from other manufacturers, including rebreathers and DPVs—with more integrations to come. Symbios is the world’s only underwater wireless ecosystem designed to scale with you, supporting the way you dive, however your diving evolves.

Symbios combines clear displays, flexible screen layouts, intuitive controls, wireless connectivity, and training-focused tools in one connected platform. Choose the device that fits your diving today, then configure it around the information and functions you need.
