Furuno FCV627

The Furuno FCV627 dual frequency color fish finder is the latest incarnation of this mid-level Furuno sounder. Like its siblings, it retains a rotary knob for gain control. A top feature found on few recreational fishfinders these days.

In our opinion, using a rotary knob to make quick and fine adjustments to the fishfinder gain is a necessity for maximizing usefulness of this machine. This feature is normally only found in much more expensive sounders.

Furuno FCV-627 Fish Finder

The FCV-627 display unit front face measures both 6.7-inches high and wide. The unit thickness is approximately 4-inches with about half that distance located in front of the panel in a flush mount situation.

The Furuno FCV627 fish finder package includes the display unit, power cable, flush mounting template, operator’s manual, single-page quick reference guide in English as well as 14 other languages, a brawny rotating single stanchion mounting bracket, and hardware to flush mount the display if you so desire.

All essential electronics are located internally in the display unit. The only remaining component needed for use is a transducer.

Several transducer options are available ranging from transom-mount units with water temperature sensing to a bronze thru-hull unit with both water temperature and speed sensors.

For our on the water testing we mounted the display using the accompanying bracket and found that it held the display unit securely in both the vertical and horizontal axis.

A pair of ports on the case back connects to the power and transducer cables using twist-lock connectors. A single ground wire connection is located on the unit back as well. This fish finder can interface with other NMEA0183 devices. One thing lacking is a NMEA2000 interface.

Screen Size and Viewability

The Furuno FCV627 has a color LCD screen measuring nearly 4.5-inches high and just over 3-inches wide. On the diagonal we measured the portrait layout screen at 5.7 inches. Screen resolution is 640 pixels vertically and 480 pixels on the horizontal plane, this is a doubling of resolution from its FCV-620 predecessor.

The display screen was bright and sharp and showed good contrast. The screen does exhibit some reflectivity. I gave it an excellent rating for daytime viewability.

A quick press of the on/off pushbutton brings up the brightness and c
