20 Most Recent Furuno FCV-582L GPS Receiver Questions & Answers

Hello Piavarone302,

I understand that you would like to know about changing your Furuno fish finder to the newer FCV 585 unit. The Transducers are interchangeable they both are compatible with one another. However, the main difference in the two units is the size of the units. The FCV-582L is 7.9 inches square and the new FCV-585 is 9.2 inches square. Both of these dimensions are for flush mounting the units.

Here are links to both of the units specs, manuals and etc.

Hello. The face of the transducer should be pointing straight down into the water to be properly installed. When it is pointing straight down, the beams of the transducer will shoot straight ahead so you will know what you are traveling into. J.

Since you have little to loose you can attempt to remove the protective coating and not attempt to replace it with a substitute material. It's not required to operate but is intended to enhance viewing in certain light conditions. Might try a window cleaner with ammonia and a little "elbow grease". Remember though, your end result could be worse than what you have now if you're unable to completely remove the film or damage the JCD panel in the process.

You likely have inadequate supply to your helm. Otherwise, there is interference being generated. Try turning things on slowly one at a time, check your batteries and ground connections.

Ability to read the bottom at speed depends on several variables. Output strength of the sounder trasducer (usually need a 1 KW to get constant bottom readings in deeper water), placement and fairing of the tranducer and any bottom appendages that may create disturbed water (air) over the transducer face. Transducers can also go bad over time.

I recommend you Give Furuno a call they have a great service Tech dept. Its free.

you need an MB1100 matching box has the 10 pin pigtail for your sounder and accepts bare wire input from your ducer
this will also ensure that all power from sonar get to ducer, but it from me if you like 847-746-0100

white and blue is correct, white is signal, but be aware that manufacturers screw this up all the time, so try it both ways, and look for pulsing data on digital meter measuring 12V, should see meter jump rhythmically, from 0 to 4-12V. Confirm presence of data to maintain sanity

those jacks are on a circuit board available from Furuno call me if you like 847-746-0100

Yes, the current model of this is the FCV 585 and it is great. The transducer will need to be changed.

Hi there,

You may choose any two frequencies between 28 and 200 kHz to fit your fishing operation. Output power is selectable from 1, 2 or 3 kW.

Hope this initial info helps.
Let me know.

There are set by you to feet, metres, 'F or 'C, knots, kph, or mph.From a bit more reading, depth is Feet, distance is Nautical Miles. Temperature you have a choice.Note: The water temperature graph can beset on or off (See page 11-4.). The temperature scale is fixed between 20-80 °F (0 to30°C).Read the manualhttps://www.furunousa.com/-/media/sites/furuno/document_library/documents/manuals/public_manuals/gp1650fdf_operators_manual_version_m.pdf..
