The Furuno FCV-585 is a dual frequency (50 kHz and 200 kHz) Color LCD Sounder featuring Furuno’s DSP technology. The FCV-585 with a transducer displays underwater conditions in 8, 16 or 64 colors on a super-bright 8.4″ LCD screen.

You’ve probably heard about digital fish finders, but aren’t quite sure what the difference is. The main difference is the filtering capabilities and auto adjustments. Furuno’s new DSP (Digital Signal Processing) technology helps adjust gain, STC “Clutter” and output power, as well as suppress main bang (the echoes just below the transducer.) It also makes the picture clearer and easier to decipher. But even the best digital filter won’t help unless you start with a solid basis, such as Furuno’s renowned fish finder technology.

The FCV585’s waterproof construction allows it to be installed on any bridge. Audio and visual alarms alert you whenever preset limits are met for water depth, water temperature and fish echoes. Selectable display modes include High or Low Frequency, Dual Frequency, Zoom, Nav Data, A-Scope, Marker Zoom, Bottom Zoom or Bottom-Lock. Furuno’s TLL (Target Lat/Lon) output allows you to interface the FCV 585 with your Furuno chart plotter so you can mark any spot you desire and save it as a waypoint, enabling you to return to it whenever you desire.
