Welcome to the world of some blow boaters mentality and there courtesy Chris. It's always fun to watch when your the only boat for miles an they figure your a buoy out there.
Look close at Simrad. There a good reliable unit that will do everything you need it to on your boat Dion.
I'm not a dealer nor do I represent there company. Just know what I have seen with the unit's I have installed. Good unit all the way around.
