Furuno DFF1-UHD CHIRP Sounder Module For NavNet

Enjoy eye-popping target definition

Designed to operate over a wide range of frequencies utilizing a
broadband transducer, the Furuno DFF1-UHD CHIRP Sounder
Module for NavNet delivers significant advancements in
signal clarity and 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.

Benefits of CHIRP sounders
Standard, non-CHIRP fishfinders operate at one or two individual
frequencies and are generally capable of detecting targets and
displaying them only within those narrow frequency bands. CHIRP
fishfinders 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 fishfinder,
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.

Furuno DFF1-UHD CHIRP Sounder Module for NavNet
Features:

• Scans across a range of frequencies – 50 kHz +/- 20 kHz, 200
  kHz +/- 25 kHz
• Enhanced depth penetration, resolution and clarity
• Precise separation between bait fish and game fish
• Enhanced ability to distinguish targets from noise using
  improved signal to noise ratio
• Improved bottom tracking at high speeds

• Reveals more fish by eliminating surface clutter and
  noise
• Accu-Fish size assessment function tells you the approximate
  size or depth of the fish below your boat
• Bottom Discrimination provides detailed graphical information
  about the make-up of the sea floor: rock, gravel, sand or
  mud
