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.
