With built-in chirp fish finding and TruEcho technology, Furuno’s GP1871F/GP1971F gives users total control by utilizing the intuitive TZtouch2 interface. Retrofits are not a problem for those using the CW transducer. Upgrade alert: The DRS4W 1st Watch wireless radar is compatible. Opt for one of two size units, either the 7-inch GP1871F or the 9-inch GP1971F — both include the latest C-Map 4D cartography.
