Opportunities
- carries out the detection and counting of fish of various species with sizes from 10 cm and more in shallow water conditions;
- forms a fan of 33 receiving "split" rays with a constant sector width of 90 degrees;
- implements the functions of echo, echo integration and post-processing system for processing of hydroacoustic data;
- installed on small boats, including small boats and lifeboats;
The user interface allows you to manage the settings of the control and display console and the transmitting and receiving path, as well as display sonar information in the following main modes: Sector, Echogram, Oscilloscope, Calibration, and EX.
Application
research workers of the Research Institute of the Russian Fishery Agency and the RAS institutes for research and quantitative assessment of aquatic biological resources.
