DFF3-UHD High Power TruEcho CHIRP

The DFF3-UHD High Power TruEcho CHIRP™ Fish Finder for NavNet TZtouch3 delivers the ability to see fish and bottom structure deeper and clearer than ever before.

Furuno’s superior digital signal processing interprets echoes from fish and underwater structures with unparalleled clarity, accuracy, and resolution, at unprecedented depths - we’re talking maximum depth scales down to 4500 meter/15000 feet!

Plenty of power and wide frequency range to Go Deep!

The DFF3-UHD provides an incredible 2kW or 3kW of power to a compatible broadband transducer, transmitting across a spectrum of frequencies to ensure that the echo returns on your display come back sharp and clear at every range. Gathering more and higher-quality data than traditional high-power CW Fish Finders, the DFF3-UHD provides significant advantages in signal clarity and target definition. This helps you find more of your target species, game fish and baitfish, even when they are tightly schooled together or near the seafloor. The DFF3-UHD transmits and receives pulses across a combination of Low, Medium, or High frequency ranges with each transmission, showing returns from bait balls and individual fish targets virtually anywhere in the water column.

High Power CHIRP Ready Transducers!

The 3kW Chirp-ready Cavity Mount CM599LH transducer is the the right tool for the job! Making the job easier and gives better results. The right tool for covering deep-water haunts of swordfish, tuna, and other species is a 2 to 3 kW, low and high-frequency transducer. The Chirp-ready CM599LH gives the deep-water performance of the low frequency down to 3000 m (10000') plus the incredible resolution that the high-frequency band delivers.

The CM599LH is packed with a twenty-four-element, low-frequency array that operates at anywhere between 28 and 60 kHz. The single, high-frequency ceramic operates at any frequency between 130 and 210 kHz and has a narrow, 8° to 4°, beamwidth.
