Radar (JMA-3400)


  • Chart overlay (NAVIONICS+)
  • Real Time Head-up Function (Constaview)
  • 12.1-inch fully dimmable display
  • High-visibility by glass-bonded display


The newest addition to the JRC radar portfolio is the JMA-3400 series. This lightweight radar has user-friendly operation system and is specially designed for fishing boats, non-international trading vessels and workboats. The system can be completed by choosing from a variety of 2 ft, 3.9 ft, 4 ft and 6 ft scanners.

The 12.1-inch dimmable LCD provides excellent visibility and durability. It reduces reflection of sunlight and shows clear images of even the smallest targets. The ergonomic keyboard offers user customizable keys. Programming the USER keys give you instant access to your favorite functions. The newly developed thin body is reduced till only 97.1 mm depth, so that it can be installed on small vessels where effective use of the limited space needs to be taken in account.

By displaying the radar image and the NAVIONICS+¹ chart in an overlapping manner, you can grasp the relationship between the radar image and the coastlines simultaneously. Naturally our patented real time Constaview functionality is incorporated into the new radar system, processing the radar image before being displayed, generating a smooth rotation when sailing in Head-Up mode. To use real-time Head-Up, own ship position information (GPS connection) and input of heading information (compass connection) is required. When changing to North-Up, the new radar image is displayed without any delay caused by the scanner rotation. By displaying the other ships moving with a tail and displaying the fixed objects such as land and buoys so that they do not pull the tail, the movements and fixed objects of other ships can be accurately read.
