had some false readings from my sea ray navigator as far as depth reporting goes. am thinking of replacing it with a new chart plotter. also i noticed that the mercury smart craft receives some of its information from the navigator (depth) as an example can i make the smart craft free standing and do they have updates for the mercury (mine is a 2003) would like a brighter screen. what is the difference in the raymarine c & e series? bob!
we were boating up in the north channel in about 100 ' of water, then all of a sudden it shows 3'. the bad thing is that my mercury smart craft and raymarine rl80c chart plotter all get their depth feeds from this unit. other than that it works fine. we have a 2003 390 motor yacht and will probably replace it over the winter. bob!
