RedNav

The RedNav navigator is part of the RedWave system. It was created specifically to determine the coordinates of divers during recreational, search, archaeological and underwater engineering operations

  • An unlimited number of divers with navigators in one water area!
  • Compact: device weight just 0.65 kg, antenna 64×64 mm, interface unit 84×118×36 mm
  • Automatic track recording (coordinates + depth + time). Track export in KML and CSV formats
  • Requires no prior setup or calibration
  • Waypoint entry before the dive, track saving after the dive, point saving during the dive
  • A fully acoustically passive device
  • 8 hours of battery life, wireless charging
  • Wireless pairing with a PC and transmission of 3D coordinates to mapping devices via Bluetooth (underwater!)

No more surfacing to mount remote GPS antennas on a cable!

The RedNav navigator is worn on the wrist or a diver's slate, while the hydroacoustic antenna is mounted on the shoulder or the tank. The device is ready to use immediately after power-on, with no additional setup.

01

No limits on the number of divers working at once or on the complexity of the water body

You can use any number of RedNav navigators in the same water area and get the coordinates of submerged objects simultaneously. Our technology works even in shallow water, without interference or a significant loss of accuracy.

02

Not just geographic coordinates!

In addition to absolute geographic coordinates, you can also read water temperature and diving depth. The device runs for up to 8 hours on a single charge.

03

Real-time coordinate tracking

Underwater, the device can pair with dive slates/tablets and transmit current coordinates to them, enabling real-time underwater map work that was unavailable until recently!

How to buy the RedNav navigator

The RedNav navigator can be purchased as part of a RedWave kit, or in addition to a previously purchased RedWave kit. The RedWave delivery set includes 4 RedBase buoys and the number of RedNav/RedNode navigators you need.
