Radar Options Menu

From a radar screen, select Menu > Radar Options.
MotionScope™: Uses the Doppler effect to detect and highlight moving targets to help you avoid potential
collisions, find flocks of birds, and track weather formations
page 87). This option is only available on GMR Fantom models.
Pulse Exp.: Increases the duration of the transmit pulse, which helps maximize the energy directed toward
targets. This helps to enhance the detection and identification of targets. This option is only available on xHD
radome and xHD2 open array models.
Target Size: Adjusts the size of targets, by adjusting the pulse compression processing. Select smaller targets
for a sharp, high resolution radar image. Select larger targets to display larger echos for point targets, like
boats and buoys. This option is only available on GMR Fantom models.
Echo Trails: Enables you to track the movement of vessels on the radar screen. This option is not available on
xHD open array or HD/HD+ radome models.
Rain Clutter: Reduces the clutter caused by rain
VRM/EBL: Shows the variable range marker (VRM) circle and the electronic bearing line (EBL) to allow you to
measure the distance and bearing from your boat to a target object
Guard Zone: Sets a safe zone around your boat and sounds an alarm when anything enters the zone
Guard Zone, page 87).
Timed Transmit: Helps conserve power by transmitting radar signals at set intervals.
