can now take a radar feed too. I have the little cp180 which works just fine for me and you can add a si-tex radar later if you wish. It would be relatively low cost compared to some of the more comprehensive systems with large displays. I just have the plotter and an old Raytheon radar. ICOM used to have a pretty good stand alone system ( if you belief glossy mag reviews) but I don't know if they still sell it.
Let me know if you need and info/help for your trip. I just moved my boat from the NS south Shore to NB Northumberland Strait area. Best regards, David
