The GPS Navigator is a handheld underwater computer designed to assist Search & Rescue, commercial and research divers navigate between pre-determined underwater waypoints and give them access to a GPS based position fix.
Navigation and positioning information is received via a small float containing the GPS antenna, and relayed to the Navigator display through a thin tether cable.
Prior to diving, software running on a Windows PC is used to create Mission files containing waypoints and markers that can assist the diver to navigate a search-pattern or efficiently swim between locations.
An immersion sensor automatically controls logging of the dive data to the Navigator’s internal storage memory, while the diver’s position, heading, depth and course history are shown on the Navigator’s display. Additional information for the currently selected mission marker is shown along with course-to-swim and distance to the marker.
The diver can add additional points of interest during the dive and these, along with the course and depth history, can be reviewed post-dive.
The Navigator has a simple and intuitive user interface allowing the Diver to quickly interpret information presented via the 3.5″ colour display, simple menu interface and five button keypad.
Powered using a compact rechargeable Nickel-Metal Hydride battery pack, the Navigator will operate for over 10 hours from a single charge, while battery packs can be easily swapped on the surface between dives in a matter of minutes.
