Does anyone have any experience with the Furuno 1623 2.2kw radarsystem? Will be installing a radar on our 28'O'Day this spring. Thisone sems to fit the bill for a relatively inexpensive unit but weare open to alternatives. We sail the Maine coast and our mainapplication is to watch out for other boats within 1-3 miles when infog. While it will be a backup for navigation we also have a Garminchartplotter. -Ron
