The FCV-38 measures the size of fish in the selected area, and displays the information in a graph that can be understood at a glance. The split-beam technology has improved the accuracy and reliability of fish size measurements and graphs (max. 3).
By analyzing the size, volume and movement of a targeted school of fish, operators can easily decide what to catch and what not to catch. It is indispensable for deciding when to go for a catch and eliminate a school of fish that are smaller than desired. In addition, it greatly contributes to the management and study of fisheries resources.
* Fish length is a reference value calculated from reflection intensity.
The fish size measurement function includes particularly useful tools to help the user keep track of targets. For example, the tool [Auto Depth] automatically adjusts the depth of the measurement area until more fish are detected if the target fish has fallen below the set limit or has left the measurement area. The tool [Auto Area] can be used to automatically move and adjust the measurement area to areas with a large number of single fish.
