RedNAV is the only device in the world that provides so-called true underwater GPS for divers. It allows divers to determine their own geographic location in submerged state wirelessly.
Operating the RedNAV in many ways similar to the work with GPS/GLONASS, receiver/tracker, but instead of GNSS satellites, it needs four RedBASE sonobuoys deployed that allow an unlimited number of RedNODE/RedNAV devices to function at the same time and at the same place.
Unique functionality and usability make RedNAV ideal for recreational diving, archeological, biological and any other scientific and technical underwater works.
