Scan-to-scan averaging, a new feature, helps aid in reduction of sea clutter and interference. Its Pulse Compression technology provides high-resolution imaging and maximizes energy to help you detect and identify targets. Auto Bird Gain helps you identify flocks of birds on the water. The GMR Fantom 256 radar have a detection range of 20’ to 96 nautical miles.
