Trails
Trails plot the historical movements of objects (Radar returns) for the time
specified in the [Trails period] setting.
Trails are subject to the selected "Reference Mode" (i.e. [True], to show
actual motion over "ground" (COG), or [Relative], to show motion relative
to your vessel).
Trails can be enabled and disabled using the [Show trails] toggle switch.
Historical object position is shown as a colored trail behind the object.
Onscreen target settings
Target settings and information are also available using the onscreen [Image
adjustment] icon.
The following target settings and information is available:

target menu options:
• [Cancel target] — The Radar target will no
longer be tracked.
• [Show CPA] — Determines whether CPA
graphics are shown.The default option is Auto
which displays CPA graphics for the target if
it becomes dangerous. You can also set CPA
graphics to On, which displays CPA graphics, if
there is an intersect point between your vessel's
current course and the target's. When set to Off
no CPA graphics will be displayed for the target.
• [Target info] — Determines whether the target's
SOG and COG information is displayed under
