Furuno FCV800 8.4″ TruEcho CHIRP CW Fish Finder

The Furuno FCV800 is a professional standalone fishfinder for commercial fishing boats, charter vessels, and deep-water anglers who need more control than a basic recreational sounder provides. Its 8.4-inch display shows a large sonar image, while TruEcho CHIRP and continuous-wave processing support a wide 40-225kHz frequency range. It is a sounder, not a chartplotter, and the transducer must be chosen separately.

The FCV800 can deliver 600W to 1kW depending on the selected transducer, so the final performance depends on matching the sounder to the hull and fishing depth. Dual-channel operation lets the operator work with separate sonar information, while RezBoost, ACCU-FISH, and bottom discrimination add useful interpretation tools. NMEA 2000, dual NMEA 0183, and wireless LAN support data sharing. The IP56 face suits a protected or semi-exposed helm.

Who Is This For?

This professional Furuno fishfinder suits commercial crabbing fleets, charter boats, offshore deep-drop vessels, and 24- to 50-foot coastal boats. It is not ideal for buyers wanting charts or a transducer-included package; sonar hardware must be selected for the boat.

Warranty & Support

The supplied specifications do not state a warranty term for this model. Confirm current Furuno warranty coverage and exclusions before purchase.

The FCV800 is the serious sounder choice here, offering a wider frequency range and higher output potential than compact fishfinders. Its trade-off is the installation work and transducer selection required to reach that performance. Choose it for deep-water or commercial fishfinding, not as an all-in-one navigation display.
