TruEcho CHIRPTM sweeps across 90 frequencies
Designed to operate over a wide range of frequencies utilizing a broadband transducer, the DFF1-UHD TruEcho CHIRPTM network sounder for NavNet TZtouch2, TZtouch and NavNet 3D delivers significant advancements in signal clarity and target definition. Standard, non-CHIRP Fish Finders operate at one or two individual frequencies and are generally capable of detecting targets and displaying them only within those narrow frequency bands. CHIRP Fish Finders transmit pulses across a wide range of frequencies, allowing Furuno’s superior digital signal processing (DSP) to display fish and structure targets with unparalleled clarity, accuracy and resolution. The DFF1-UHD uses a precise sweep pattern across 90 frequencies (50 kHz +/- 20 kHz, 200 kHz +/- 25 kHz) within a long-duration transmission. The equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional Fish Finder, resulting in more energy on target. The results are up to 5x greater resolution and depth capability than comparably powered, standard Fish Finders due to the advanced signal processing of the return echo.
Enjoy eye-popping target definition
The clear presentation of the DFF1-UHD marks individual game fish and bait fish, even when tightly schooled together or very near the sea floor. The sound energy transmitted by the DFF1-UHD into the water is up to 1,000 times greater than a conventional Fish Finder, resulting in more energy on the target. Utilizing our Furuno Digital Filter (FDF) signal processing results in up to 5x greater resolution and depth capability than comparably powered standard Fish Finders. Furuno is evolving CHIRP technology to the next level by adding unique capabilities, such as Bottom Discrimination and Accu-Fish.
Furuno Digital Filter (FDFTM) Fish Finder
Furuno Digital Filter (FDF™) Fish Finders feature advanced filtering capabilities and digital auto tuning, which eliminates noise. Furuno FDF Fish Finders deliver the ability to spot individual fish with clarity, accuracy and detail. Whether in shallow or deep water, Furuno FDF Fish Finders give you what you would expect from a Fish Finder at all times.
Know more about the fish under your boat
Furuno’s award winning network Fish Finders offer a unique fish size analyzer function, ACCU-FISH™. The ACCU-FISH™ algorithm analyzes echo returns to compute individual fish size and display it on the screen.
Classify the seafloor with Bottom Discrimination Mode
Utilizing input from the Network Fish Finders BBDS1 or DFF1-UHD, the bottom discrimination display will be shown in the following four categories; "Rocks", "Gravel", "Sand" and "Mud", either in dedicated graphics or colors with corresponding probability. This information is helpful in spotting rich fishing grounds where you can boost your catch of the day.
