Furuno Echosounder FCV-800
Standalone echo sounder with 600 W or 1 kW transmission power and the option of either a dual-frequency 50/200 kHz transducer or a CHIRP transducer. A dual-frequency transducer enables functions such as bottom discrimination and ACCU-FISH™, which indicates fish size. Compatibility with a wide range of transducers simplifies upgrades to the FCV-800.
- 600 W or 1 kW transmit power for excellent range
- High/low-frequency echosounder: 50 / 200 kHz
- Supports combination of CW and CHIRP transducers
- Heave stabilization when connected to a satellite compass
- Bottom hardness output to plotter
- RezBoost™ for enhanced performance
- ACCU-FISH™ for fish size indication
- Broad selection of compatible transducers
The FCV-800 supports either a dual-frequency transducer or a CHIRP transducer. It features selectable 600 W or 1 kW transmit power (depending on transducer) and has two transducer ports. A 50/200 kHz dual-frequency transducer provides access to all built-in functions.
The FCV-800 also allows for a combination of a traditional CW (Continuous Wave) transducer and a single-frequency CHIRP transducer, unlocking Furuno TruEcho CHIRP™ technology for improved noise suppression, enhanced detail, and superior target separation.
You can also connect two FCV-800 displays to the same sonar system. One acts as a slave unit and can connect wirelessly within a 10-meter range.

A CHIRP transducer gives access to Furuno TruEcho CHIRP™ technology for better noise handling, higher fidelity and sharper separation.
Recommended Transducers for FCV-800
To unlock the full range of features and performance, we recommend:
- 1 kW dual-frequency transducer: B260, 50/200 kHz, 1 kW, 19/6°
Alternative 600 W dual-frequency transducers:
- 600 W svinger med høy/lav frekvens: 520-5PSD, 50/200 kHz, 42/12°
- 600 W svinger med høy/lav frekvens: 520-5MSD, 50/200 kHz, 45/12°
CHIRP transducer
When connected to a CHIRP transducer, the FCV-800 utilizes Furuno TruEcho CHIRP™ technology. This enables better noise rejection, more detail, and improved target separation—especially in shallow water. We recommend the following CHIRP transducer:
- 1 kW transducer: B265LH-FJ12
RETROFIT-FRIENDLY
The FCV-800 is compatible with a wide range of standard transducers. When upgrading from an older sounder, you can often reuse your existing transducer, and later upgrade to a newer model to unlock full functionality and performance.
HIGH PERFORMANCE AND RICH COLOR GRADATIONS
The FCV-800 displays echoes with more refined color gradations than previous models, reflecting its high performance and target separation capabilities. It's easy to distinguish bottom, baitfish, and game fish at a glance.
A FEATURE-RICH ECHOSOUNDER
- TruEcho CHIRP™ - exceptional noise-processing and sharp detail across a wide frequency band, that the CHIRP transducer enables
- RezBoost™ signal processing - improves performance and resolution with traditional CW transducers
- ACCU-FISH™ - displays fish size and depth
- Bottom classification - identifies seabed type across four categories: rock, sand, gravel, and mud
- New! Bottom hardness output - transmits data to external plotters such as TZ Professional and NavNet
- New! Expanded color gradations - better differentiation between echoes from bottom, baitfish, and targets
- White line function - highlights the seabed top line in white for easier interpretation
- Customizable alarms - set alerts for depth, fish echoes, swimming speed, and more
- TLL (Target Lat/Lon) output - mark fishing spots with metadata like depth, water temperature, fish size, and bottom type after which you can export the data to plotters such as TimeZero Professional or NavNet
- New! Wireless connectivity - optional wireless secondary display for easier installation

Expanded color gradations allow for easier differentiation between echoes from bottom, baitfish, and targets.

ACCU-FISH displays fish size and depth.
