Furuno DFF1-UHD TruEcho CHIRP Sounder Module Network Fish Finder

The Furuno DFF1-UHD is a TruEcho CHIRP network sounder module (fish finder) designed to operate across a wide range of frequencies with a broadband transducer. It delivers improved signal clarity and target definition, clearly marking individual game fish and bait fish, even when they are tightly schooled together or very near the sea floor.

Benefits of CHIRP Sounders:

• Wide frequency coverage: Standard, non-CHIRP fish finders operate at one or two individual frequencies and detect targets only within those narrow bands. CHIRP sounders transmit pulses across a wide range of frequencies, allowing Furuno's digital signal processing (DSP) to display fish and structure targets with greater clarity, accuracy and resolution.
• Longer transmission: Typical non-CHIRP fish finders operate at a maximum duty cycle of 1%, so the transmit pulse is short and limits the total energy sent into the water column. The DFF1-UHD instead uses a long-duration transmission.
• Precise sweep pattern: The DFF1-UHD sweeps across 90 frequencies (50 kHz +/- 20 kHz and 200 kHz +/- 25 kHz).
• More energy on target: The equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional fish finder, and advanced processing of the returning echo yields up to 5x greater resolution and depth capability than comparably powered standard fish finders.
