The target trails feature generates a monotone or gradual shading

afterglow on all objects on the display. The trails are useful in

showing own ship movement and other ship tracks. True

or Relative

echo trail is available in Relative Motion. (only True echo trail is

selectable in True Motion)
Even if the plotting interval or display setting are changed, trails

remain on the screen and the trail length will change according to the

new setting.

*Heading sensor required

Target Trail

The radar incorporates a Video Plotter that displays electronic charts,

plots own and other ship's tracks, enables entry of waypoints/routes

and makes a radar map. The chart may be displayed in combination

with radar images.
It is compatible with FURUNO or Navionics charts.

Chart Overlay

The radar has three modes to display the echo area: CIRCLE, WIDE,

and ALL.
With "All" Echo Area Mode, the entire screen is filled with an echo image.

Its full-screen echo presentation capability allows the operator to observe a

wider overview of the surrounding area, a function vital in fishing operations.

Long Trail Mode

Target trails are memorized for the duration of your

selected trail time from 15 seconds to 48 hours.

Narrow Trail Mode

Target trails can be painted with thinner lines if desired.

This is useful when there are a lot of targets on the screen

that need to be easily distinguished.

Multi-color Trail Mode

The target trails change their

colors in 12 gradations. The

color changes as time passes.

This makes it easier to know

the movement and speed of

targets.

Own Ship Trail OFF

This radar has functions to automatically prohibit the

unwanted trail which is generated around your vessel

according to the sea clutter level.

Trail Eraser

The generated trails of other vessels or sea clutter can

be erased with the trail eraser. It is useful for deleting

unwanted trails that are near

your vessel.
