Furuno's Newest Fish Finders Utilize Digital Technology

In 1948, FURUNO introduced the world’s first commercially available fish finder, revolutionizing how fishermen found their catch. Fast forward to 2006, where FURUNO’s famous fish finder technology now implements the latest in digital filtering for enhanced detail and accuracy, introducing the new FCV-585 and FCV-620 digital, dual-frequency fish finders.
FURUNO’s new DSP (Digital Signal Processing) technology adapts to your fishing environment by adjusting gain, STC and output power, as well as suppressing main bang (the echoes or clutter just below the transducer). It also makes the picture clearer and easier to decipher between baitfish and larger target species. The DSP filter optimizes the gain to suit the search range. For example, when searching in deep water, the pulse length is made wider and the reception band is made narrower, allowing for better and clearer detection at the deeper range. This is perfect for finding bottom fish, because the digital filter separates the noise from the actual seabed structure, allowing you to see the target fish close to the seabed.
Shallow water detection is also enhanced with the new DSP technology by suppressing surface clutter mainly caused by the vessels propeller. Together with its exceptionally fast transmission rate of 3,000 times per minute at the range of 5 m, this new technology enables you to identify bait pods and individual fish targets right under the boat.
The FCV-585 sports an incredibly bright and large 8.4' VGA sunlight viewable 256-color LCD that will stand up to the harshest conditions. The FCV-620 employs a 5.6' QVGA display with the same characteristics as the FCV585. Both have a wide viewing angle and can dis"
