I have an Lowrance Elite 4 with the Navionics Gold card. I have to say I'm pretty disappointed in it. As far as detail goes it doesn't even show that I'm in the water on some of the smaller rivers around here, even zoomed in all the way. I've never had a combo unit before. Is this normal or am I doing something wrong or expecting too much out of it? In the ICW and bigger water it seems to be fine.
