Fish Sizing Echo Sounder Sonic KSE-300
Echo sounders are designed to transmit sonic waves from a transducer and receive the echo reflected from fish or the bottom of the sea. On previous echo sounders, images were adjusted by the TVG volume and gain volume, so that the reflected echo could easily be seen on the echo sounder picture.
This Fish Sizing Echo Sounder needs no TVG volume adjustment, and it automatically and accurately corrects the sonic wave attenuation under the sea. Fish schools of the same density are displayed in the same color regardless of the depth.
- Detection of a single fish with high accuracy.
- Zoom function with biomass information.
- Controller designed for this system.
- Data recording function installed as the standard feature (row data).
- High precision digital TVG.
- Function to determine the sea bottom level.
- Fast and easy operation.
- Improved bottom detection functionality.
- Menu system in multiple languages.
