Target options screen
The
Target Options
screen controls how
target data is displayed, and how the target
alarm works.
Detail
Choose the data that labels the target on
the radar image:
•
name of the target
•
name and the target’s COG and SOG
•
name and the target’s CPA and TCPA
•
all data
•
none
Generally, you may wish to display only
the target name, to avoid cluttering the
screen and covering the display of other
radar echoes.
Tracks
Targets can leave tracks showing their
previous positions and their motion.
Choose the length of the tracks from 1
minute to 15 minutes, or turn them off.
Sorting
Choose how the targets list is sorted (same
as the menu key on the
Targets
screen).
Bearing
Choose whether bearings are displayed as
relative to the vessel’s heading, or as
absolute bearings (north = 000°), or as a
clock dial (“target at 4 o’clock”)
