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.

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.
