Olex OS1 - Fish mapping echosounder


Olex introduces OS1 - our own echosounder.
The OS1 blackbox, connected to an Olex with the OS key and a transducer, provides an echosounder with a unique twist. An adjustable window on the screen, shows the fish, and bottom just like a traditional sounder. Using the OS software mudule, Olex remembers every ping and creates a map of where the fish has been so that you can predict where it will be in the future.

  • Max transmitter power : 1kW.
  • Range of frequency: 40 to 210 kHz.

  • Shows fish detections for all years.
  • See the OS1 installation manual for more product specifications.

Fish mapping


The new functions for fish mapping provides a unique insight into how the fish migrate and how they move between seasons.

The historical fish detections, combined with self-measured seabed maps, let the fisherman discover and research on how bottom details tend to attract fish, or not.
