Furuno 582L sonar unit in good condition removed working during an upgrade. Screen looks clear and bright. All knobs work and functions work. The unit was flush mounted. Listed as good and not excellent because the screen although does not have any sun damage looks grainy on the white background.   Maybe not noticeable to some but I have seen hundreds of screens and I notice it and want to disclose.  It is being sold at a reduced price for this reason.  I think the unit is fine long term, the pictures are of the actual unit in demo mode and with white background. 

All other functions of this unit have been tested and work as new.
