Dedicated keyboard

The new JLN-652 allows you to carry out all operations simply by using the keyboard. The layout has a full complement of keys, including direct STC and GAIN, to adjust noise under surface of the water level and receiver sensitivity respectively. The keyboard also has one-touch menu keys to access different display modes instantly as well as a special frame-selector to navigate quickly through a variety of menu items on display.

Fish finding

You can view fish echoes in four-directions, two-directions ahead, or in any one direction, allowing for easy fish tracking. Just as any typical fish finder, you can set the display to present fish echo and seabed condition simply by adjusting the sensitivity.


There is a wide range of alarms available on the JLN-652. With all alarms, for example, when depth becomes shallower than the parameter set, a warning message pops up, allowing the operator to take action, contributing to safer navigation and more efficient fish finding.

High resolution display

The Doppler current meter not only measures data with unmatched accuracy but also features a high resolution output of 1024 by 768 pixels (XGA) which provides excellent and efficient tidal analysis.

Black box configured

The JLN-652 consists of a display (option), processor and keyboard, allowing for a flexible installation approach in confined spaces. For those who prefer to specify their own display, the JLN-652 allows you to choose what type and size of display to connect to the unit, as long as it supports XGA.
