The compact, battery-powered unit is based on EvoLogics 18/34 modems. It is mounted directly on the diver’s gear or integrated into the GAVIN scooter for unobstructed acoustic transmission. It continuously tracks the diver’s position and transmits data to the surface buoy in real time. Rugged, lightweight and diver-friendly, it delivers precise positioning and reliable acoustic communication even under challenging conditions.

The diver display connects to the diver tracker with a cable. It is a wrist-mounted, quick-release tablet running the intuitive SiNAPS Dive interface. Fully functional down to 150 m deep, it shows the mission map, positions of other divers and vessels, points of interest and chat messages, while also enabling divers to capture and share photos during the mission. Operated with a stylus designed specifically for underwater use, the display allows precise interaction with the interface, making it easy to select elements and respond promptly to incoming messages or task updates.

The floating USBL Buoy is the central surface node for acoustic positioning and mission management. A compact, all-in-one battery-powered unit with a USBL antenna, GNSS and SiNAPS software running on its onboard PC, it keeps the underwater team connected and tracked in real time. Ready for immediate deployment from vessels or fixed stations, it provides reliable mission data and ensures smooth coordination between divers and surface teams.

The Sonobot 5 unmanned surface vehicle equipped with a USBL arm is a mobile alternative to the stationary buoy. Operating as a surface node, it can actively follow diver teams, keeping them within optimal range for positioning and communication. Like the buoy, it integrates a USBL antenna, GNSS and onboard PC running EvoLogics’ SiNAPS software, providing real-time tracking, mission control and data exchange. By combining these functions with the mobility of an autonomous surface drone, the Sonobot ensures continuous coverage and extends operational flexibility for diver missions.

The SiNAPS positioning software serves as the mission control platform for surface teams, displaying live diver positions, managing points of interest, and enabling two-way messaging. Supporting real-time data exchange between multiple divers and surface crew, it creates a shared situational awareness environment for all participants. By providing the surface team with a clear, real-time view of the mission area, SiNAPS helps to coordinate tasks, respond instantly to changing conditions, and maintain full operational control. SiNAPS can be opened in any modern web browser on devices within the local network of the USBL Buoy and used on multiple screens at once for shared mission oversight.

The SiNAPS Dive software is optimized specifically for diver displays. Its clean, intuitive and user-friendly interface clearly highlights essential mission data, enabling divers to interact quickly and efficiently by using a stylus. The software ensures that all divers share and see the same live data as the surface team, enabling perfectly synchronized actions underwater. Designed to enhance navigation and communication during underwater missions, SiNAPS Dive provides real-time tracking of diver positions, mission details, and points of interest. Divers use the display to manage mission settings, monitor tracking data, capture photos, and communicate seamlessly with team members.

In this setup, the acoustic modem unit is attached to the diver’s scuba tank, while the display is worn on the diver’s wrist. This arrangement offers excellent flexibility and mobility during missions, making it ideal for standard diving operations where ease of movement and quick interaction with the diver display are crucial. Divers can effortlessly monitor mission data and communicate while maintaining full control over their equipment

The Diver Navigation System is available fully integrated with the GAVIN NT Scooter (40V) for missions that require extended range and high maneuverability offered by dive propulsion vehicles. The acoustic modem tracker is built into the scooter directly, and the display is securely mounted on the vehicle, keeping all components firmly in place. The integrated modem does not affect the scooter’s performance, making this configuration ideal for extended-range operations, rapid transit to remote sites, and conserving diver energy during long or physically demanding missions.
