Symbios HUD Dive Computer

Yes. The Symbios HUD functions as a complete dive computer on its own and does not require a separate handset for normal diving operations.

The industry-leading design of the Symbios HUD stands apart from other HUD systems through its unmatched size-to-weight ratio, unprecedented flexibility, and pioneering connectivity. The wireless, ultra-light, compact design allows it to be mounted directly to a dive mask, making it equally suitable for recreational, technical, and rebreather diving. It can be used as a standalone computer or connected to a growing range of Symbios-enabled devices, including Tank Pods, rebreathers, GPS devices, DPVs, and more.

The HUD displays essential dive information such as depth, time, decompression status, ascent rate, gas information, compass data, and tank pressure when paired with compatible Symbios devices. Additional information may include CCR sensor data, battery status, oxygen cylinder pressure, system warnings, and dive buddy information when connected to compatible open-circuit or rebreather systems within the Symbios Ecosystem.

Yes. The Symbios HUD supports recreational, technical, and rebreather diving, providing real-time information directly within the diver's field of view.

The Symbios HUD mounts to compatible dive masks using a dedicated mounting system, positioning the display close to your line of sight while remaining unobtrusive. Step-by-step installation instructions are available in the Symbios HUD Installation Guide and the video tutorials below.

No. The HUD is designed to remain outside your primary field of view while allowing quick access to critical information with a simple glance.

Yes. The HUD integrates with the Symbios Ecosystem and can display rebreather information when connected to compatible Symbios CCR components.

Yes. When paired with a compatible Symbios Tank Pod, CCR Pod, or rebreather system, the HUD can display real-time cylinder pressure and gas consumption information.

Yes. Divers can customize display layouts and data fields to prioritize the information most relevant to their diving preferences and objectives.

Unlike wrist-mounted computers, the Symbios HUD keeps critical dive information within your field of view, reducing the need to look away from your environment while maintaining situational awareness.

Yes. The Symbios HUD includes dedicated Personal and Buddy screens that allow divers to view critical information for themselves and nearby team members when connected through compatible Symbios devices. When both divers are equipped with compatible Symbios systems, the Buddy screen can display information such as gas pressure, PO₂ data, and other life-support information, helping improve team awareness and communication throughout the dive.

The Symbios Handset provides real-time decompression insight through a visual Gradient Factor chart. This full-color graph allows divers to see how decompression evolves throughout the dive, monitor the leading tissue compartment, and better understand the relationship between tissue loading and decompression strategy. The result is greater awareness and a clearer understanding of decompression status than traditional numerical displays alone.

The HUD features a rechargeable battery designed for extended use, allowing it to be recharged between dives.

The Symbios HUD places critical dive information directly within the diver's field of view, reducing the need to look away from the subject, task, or environment. This can be especially valuable for underwater photographers, scientific divers, public safety teams, instructors, and other professionals who need to maintain focus while staying informed throughout the dive.

Yes. Firmware updates can be installed through the Symbios App or via a USB connection to a PC, ensuring access to the latest features and improvements.

Yes. The HUD connects to the App, where divers can configure settings, manage dive profiles, review dive logs, and access additional features.

When paired with a Symbios Tank Pod, the patented Trim Indicator provides immediate feedback on body position and trim throughout the dive. This feature can be particularly valuable for training, skill development, underwater photography, scientific or cave diving, and high-performance technical diving, where maintaining an efficient body position is critical.

Yes. The display is designed to remain clear and readable in a wide range of diving conditions, including low-visibility environments.

Yes. Many divers choose to use both devices together, combining the always-visible HUD display with the expanded information and controls available on the Symbios Handset.

The Symbios Handset includes industry-leading training tools designed to help divers develop skills, refine procedures, and prepare for more complex dives before entering the water. Through the Halcyon App, divers can simulate dives, gas switches, decompression schedules, and emergency scenarios. A unique, Halcyon-only Training Mode allows divers to practice decompression procedures and gas-switch protocols in a safe environment without creating a decompression obligation, making it a valuable tool for both formal training and ongoing skill development.
