Buoys and other small echoes will remain clearly visible when using a new river radar that minimises waves on wide water and offers a sharp display.

Alphatron Marine’s JMR-611 features a GPS compass, smart calculation technology, an aerodynamic scanner and an associated modified motor.

It is equipped with the Echo Border function for a sharp display of the radar echoes and in combination with the Expansion function, the echoes will be displayed with a clear outline.

JMR-611 is the first river radar to meet the stricter requirements for maximum reflection from radar monitors. There is a choice of two different fully dimmable monitors, the standard 19-inch LED monitor with a black aluminium front, and the all-glass 19-inch LED monitor, where the LED panel is optical bonded to the glass for maximum performance.

Multiple options

Depending on the available space on board and the desired sharpness of the picture, different scanner units are available in sizes 6, 7 or 9ft.

Alphatron Marine has re-processed and improved certain functionalities from the JMA-610 model in this new radar, such as the prediction lines, docking information and image recording.

New developments include the 6 and 7ft antennas featuring an aerodynamic design, suitable for all weather conditions.

For fast ships, the rotational speed of the antenna can be easily switched to high speed.
