Features

Twist display

You can view the current direction and speed in up to 100 layers with the twist mode. With this advanced feature, an operator is able to anticipate current speed and direction, enhancing the timing on when to deploy the nets in the water. Naturally, the twist display mode is accompanied with a wide range of information, such as current speed range, depth range, temperature and so on.

Five depth layers

The JLN-650 Doppler current meter allows continuous display of tidal currents at five depths layers (A,B,C,D,E) simultaneously, of which each layer is measured in four directions: port ahead, starboard ahead, port astern and starboard astern. The user can select the depth of each layer, showing different information. You can also select bearing1 displayed as North-up (with true north at the top of the display) and Head-up (with bow at the top of the display)

Image:Five depth layers

Bottom layer auto shift

The bottom layer (E) has the ability to automatically shift and display the measuring depth according to the ups and downs of the sea bottom. This is a great source of information for efficient fishing and for the safety of your nets.

Automatic bottom current tracking

Normally run automatically, the new JLN-650 allows bottom tracking with depths up to approximately 400 meters2, measuring direction and speed relative to the sea bottom. If sea bottom becomes too deep, it automatically switches to water tracking mode or through GPS mode, depending on user selection.

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 the type of fish or sea conditions simply by adjusting the sensitivity.

  • Heading input necessary
  • Maximum tracking depth may vary according to sea bottom conditions

Easy operation

Display mode

This Doppler current meter has 15 comprehensive and easily readable display modes for efficient tidal analysis. With our dedicated keyboard you can navigate through all common used tasks effortlessly.

Dedicated keyboard

The new JLN-650 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 specialframe-selector to navigate quickly through a variety of menu items on display.

Easy interfacing

The new Doppler current meter integrates two-way interfacing, allowing you to easily connect a wide range of additional (NMEA) navigation equipment. Up to 1000 memory points of current and track data can be saved on USB memory.

Alarms

There are a wide range of alarms available on the JLN-650. 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.

System

Black box configuration

The JLN-650 consist of a display, signal processor and keyboard, allowing for a flexible installation approach in confined spaces. For those who prefer to specify their own display, the JLN-650 allows you to choose what type and size of display to connect to the unit. You can choose between LCD and CRT, as long as it supports XGA.

Transducer

JRC's new Doppler current meter operates with a new 125 kHz transducer, designed to minimize side lobes. The transducer is available with a stuffing tube, both for iron and FRP hull installations. The standard transducer cable length of 25 meters can be extended to a maximum of 100 meters. (special cable required)
