FCV800 CHIRP Fish FinderThe 8.4" FCV800 includes all of the functionality of the FCV600 but features dual transducer ports, allowing for the simultaneous use of both CHIRP and CW channels. The dual transducer ports of the FCV800 offer the best of both worlds. Features such as Furuno's Accu-Fish fish size assessment tool and Bottom Discrimination to display what kind of material the bottom is composed of require a dual-frequency CW transducer, while Furuno's TruEcho CHIRP delivers greater detail and target separation for baitfish, game fish, and structure.With the FCV800's ability to drive both TruEcho CHIRP and CW options at the same time, those sought-after CW-only features can be combined with TruEcho CHIRP's frequency-modulated signal to deliver those exclusive Furuno features while providing better resolution for targets on the screen.
