Garmin 0100136500 GMR Fantom™ Antenna Array Only, 4′ White

GMR Fantom™ solid-state radars use MotionScope™ technology to detect and highlight moving targets in different colors, which helps you avoid potential collisions, find flocks of birds and track weather. Their Pulse Compression technology provides high-resolution imaging and maximizes energy to help you detect and identify targets. True echo trails gives you a fading trail on moving targets while accounting for the movement of your boat. Auto bird gain helps you identify flocks of birds on the water.
