Fish Finders Basics
Exploring the origins of fish finders and the principles behind their technology.
- Fish Finder
8.4" COLOR LCD FISH FINDER
Model FCV-800
Boost your catch with TruEcho CHIRP™, Furuno's revolutionary broadband, combining multi-frequency features utilizing multiple transducers!
The FCV-800 combines the power of TruEcho CHIRP™ with a host of revolutionary identification technologies to clearly distinguish fish from other structures, such as the seabed or reefs. Additionally, it allows you to use TruEcho CHIRP™ and CW technologies, such as bottom discrimination and ACCU-FISH™, together for added capabilities.

Features
TruEcho CHIRP™
Traditional CW (Continuous Wave) Fish Finders transmit a signal composed of a single frequency, while CHIRP Fish Finders transmit a linear frequencymodulated signal - a wave with a frequency that increases over time. The FCV-600 and FCV-800 can utilize a broadband transducer to transmit across a spectrum of frequencies, resulting in better target resolution. With Furuno’s TruEcho CHIRP™, you’ll see greater detail and target separation for baitfish, game fish, and structure.
COMBINE CW & TruEcho CHIRP™ FOR ADDED CAPABILITIES
By combining CHIRP and traditional CW transducers*1, you’ll see crisp CHIRP echoes on the screen while the ACCU-FISH™ and Bottom Discrimination functions from your CW transducer work in the background, overlaying important information on your CHIRP returns. You will be able to see fish targets, fish size assessment, fish depth, and bottom composition.*2 Up to three frequencies can be saved as preset selections.
- FCV-800 Single Frequency CHIRP only
- MF or HF CHIRP
COLOR EXPANSION
With Color Range Expansion, the range of identifiable echoes is expanded so you can intuitively identify bottom fish from the seabed. Reefs, structure, and fish near the seabed are shown in slightly separated colors, making it easy to tell structure from fish at a glance.
NEW Colors
Sunlight and Yellow color schemes offer enhanced visibility under bright sunlight conditions.
WIRELESS CONNECTIVITY
A second display can be installed to show the echoes and nav data from the FCV-600 and FCV-800 via wireless network, so you can monitor the underwater situation from the stern or bow while fishing.
Remote Display by Apps
The FCV-600/800 has a built-in Wireless LAN that allows you to display fish finder echoes on a smart phone or tablet device. The fish finder echoes can be viewed and operated by Android™ or iOS/iPadOS devices, even from a distance inboard. The compatible applications are listed in the table below.
- When utilizing the TZ iBoat app and NavNet Viewer app, be sure to use FCV-600/800 software version V2.05 or later.
