A reliable classic, the SL500 delivers data mid-channel, yet is mounted pier or shore-side for quick access and maintenance, without the use of divers or boats. It is lightweight and easier to mount than comparable systems, yet delivers horizontal ranges up to 120m (400ft). Ideal for:

  • Large rivers, estuaries, and large water delivery canals
  • Bridge and pier-side monitoring of tides and currents for port safety, vessel navigation, and weather stations
  • Offshore platforms
