New KSE series offers efficient fishing and resource management.

  • Fish length graphs are more smoothly displayed in higher definition Higher definition is achieved by an increased data amount that’s 1.5 times more than before, as well as by a reduced pulse width.

  • Operability is greatly improved through a dedicated controller.
  • Multi-screen Up to five types of echograms can be simultaneously displayed.
  • A function to record raw data is available as a standard feature.
  • Introduction of an ultra-high-precision digital TVG as leading-edge technology.
  • Frequency difference method, This is effective for extracting the target fish school.

Frequency difference method

The “frequency difference method” is a function used to draw images by extracting only the data showing the difference between frequencies A and B.

Raw data recording

To meet the requirements of users who wish to use this system not only for selective fishing and resource management but also for biomass evaluation, a new function to record raw data has been added. The data can be recorded with one click in a USB flash drive. In compatible with the KFC series, analysis software corresponding with Echoview* is required.
