Sizing Echo Sounder Type KSE-300 For Fishery
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.
Interference elimination
The images below show the interference elimination function of the KSE-300 frequency : 70kHz, recorded in an actual sea area in the order of OFF, ON, OFF.
