There’s been a multi-frequency fight going on between Garmin vs Raymarine vs Simrad over who can CHIRP the loudest, and unless you live in a cave and your boat is a dugout canoe, you've heard about these CHIRP fishfinders by now. They send multi-frequency blasts into the depths instead of pinging away with merely one or two frequencies, and the net result is better target definition and far better range. Now Furuno has entered the fray, with the DFF1-UHD TruEcho.
Although Furuno isn't always the first to market with a new technology like this, they do have a reputation—and a well-deserved one—for refining and improving a new technology before they bring it to the market. (Note: when they apply that technology to a new unit they also tend to make ‘em bullet-proof). So it shouldn't be a big surprise that this is not just a late-arriving also-ran. Furuno supercharged their CHIRP with a couple of cool features that no one else offers. First is Bottom Discrimination Mode, which puts detailed bottom type info on-screen. The bottom is classified as mud, rock, sand, or gravel, and an icon displays which type you’re going over at any given time. Second is Accu-Fish, which tells you the size of the fish you’re looking at. It can ID fish sizes from four inches to six feet, and also displays the exact depth of the target.
The DFF1-UHD works with a NavNet TZ Touch or NavNet 3D multifunction displays, or can be tied into a Navnet-supported Ethernet network. In either case, upgrading to a CHIRP transducer will be in order, and in some cases a software upgrade is in the cards, too.
