I am using a Garmin 192C currently but am going to change boats so I was going to upgrade. I have always used Garmin and don't intend to change. I am thinking of something in the $500-$1000 range. So I go to the WM catalog just to see what is out there and there is this dazzling assortment of units available. Anyone want to offer real world advice on a practical unit in that lower price range. I have a BlueChip chart for canada into alaska so will keep that and use it on whichever Garmin I buy. Thanks in advance.
