In 2006, Furuno laid the groundwork for new sounders with the introduction of their FCV620 and FCV585 digital fish finders. These units featured FDF (Furuno Digital Filter) Technology. FDF is the latest in digital signal processing technology that delivers noise-free underwater images. In less than a year, Furuno's FDF technology was so well received that it won the National Marine Electronics Associations 2006 Best Fish Finder award for the FCV585. Now, Furuno is bringing this same FDF technology to their NavNet system with the new DFF1 Digital Fish Finder module.
