MotionScope™ Doppler Radar Technology
The MotionScope feature uses the Doppler effect to detect and highlight moving targets
to help you navigate around other boats or severe weather, or toward fishing spots where
birds are feeding at the surface. The moving targets are color-coded so you can tell at
a glance which targets are heading your way and which are heading away from you. On
most color schemes, green indicates targets moving away from you and red indicates
targets moving toward you.
Select MotionScope™ to toggle MotionScope on/off.
