Water current

Realfish current buoy

We offer the best solution in the market for real-time water current measurement. A Nortek doppler instrument is attached to the buoy and allows for measurement of currents in three or more depths down to 50 meters. Additionally, by connecting oxygen and salinity sensors to the buoy, you will also get valuable reference data for the measurements you collect inside the cages.

The buoy is built to withstand rough handling and includes a reflex label, a radar reflector and an option for a light beacon. All equipment is waterproof and it is easy to change the batteries.


  • Used in planning and risk assessment when performing operations on site
  • Reporting to authorities
  • Realfish has its own module used for optimization of feeding
  • Documentation of water current conditions
