Clearly defined and highly colorful image plus high resolving power have been made possible by the use of new signal and image processing technology so that it has become easier to find fish school distribution and density. The images are sharp and clearly discernible due to decrease in noise generated by the reflections from the sea surface.

The JFS-3721 is a color scanning sonar with two-frequency. This is utilized as a response to the fishing needs of large and medium size tuna and bonito clippers. This sonar makes it much easier to locate and identify schools of fish.

The JFS-3721 is an ideal sonar capable of detecting schools of fish, whether those shcools are nearby or further away at distance. The feature is enabled with both performance of high-output low-frequency and high-frequency obtaining clear and high-resolution echo image.

With a two-frequency transducer and compact transceiver, this JFS-3721 sonar takes up less space than previous equipment because it requires only a single hoisting device. This feature also makes the equipment easier to install.

The device offers the advantages of two dedicated low-frequency and high-frequency indicators that display a variety of information such as ship speed, the course of the vessel, and its location. This capability will make fishing operations more efficient than ever.
