Furuno Debuts CHIRP-Enabled Fish Finder

February 20, 2013

The DFF1-UHD features TruEcho CHIRP, Furuno’s professional-grade broadband fish finding technology.
Designed to operate across a range of frequencies using a CHIRP transducer, the DFF1-UHD delivers improved signal clarity, resolution and target definition, helping to find target species, game fish and bait fish, even when they are tightly schooled together or near the sea floor. Two new features of the DFF1-UHD are Bottom Discrimination and Accu-Fish technologies.

Bottom Discrimination Mode provides you detailed graphical information about the make-up of the bottom. This is accomplished by classifying the bottom as one of four types: Rocks, Sand, Gravel or Mud, as well as assigning and displaying an icon or symbol for that bottom type. Knowing the make-up of the bottom provides information to help locate rich fishing grounds, potential hazards, and even good anchoring spots. The bottom details are shown on the screen in either a graphical representation or probability graph.

Accu-Fish is a fish size assessment function that can tell you the approximate size of the fish below the boat. Fish symbols appear on screen, along with the size of the fish or the depth where it found the fish. It can detect fish size from four inches up to about six feet long, in depths of seven feet to over 300 feet of water. Other DFF1-UHD features include A-Scope, Alarm (fish, depth or temp) and enhanced automatic cruising or fishing modes to suit your style of boating. A CHIRP transducer is required, and optional speed/temp sensors are also available.

The DFF1-UHD TruEcho CHIRP Fish Finder transmits and receives pulses across a range of 90 frequencies (50kHz +/- 20kHz, 200kHz +/- 25kHz) within each transmission. The equivalent sound energy transmitted into the water can be up to 1,000 times greater than a conventional Fish Finder, resulting in more energy on target which provides greater resolution and depth capability than a comparably powered
standard Fish Finder. Furuno’s digital signal processing (DSP) interprets the returned echoes from fish and underwater structures with unparalleled clarity, accuracy and resolution.

The Furuno DFF1-UHD connects directly to any NavNet TZtouch and NavNet 3D MFD, or it can be connected to a NavNet supported Ethernet network. A software upgrade may be required to utilize this new Fish Finder. Upgrading to TruEcho CHIRP capability can be an easy transition for current installations. The DFF1-UHD will function at a fixed frequency with many existing transducers.
