Furuno DFF1-UHD TruEcho CHIRP Network Sounder

TruEcho CHIRP^TM 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.
