Fishfinders/elec trolling motors

Went down the Garmin road years ago with a GPS. Found out all of the software was proprietary. When they decide to discontinue a format, it's gone. Since then, I have opted to use equipment that is Navionics compatible. Keeps the options open. I have an old Lowrance unit that I still use. LOL.....But I don't really try that hard to catch.
