I have searched and researched and still cannot decide what to get. It is time for an upgrade for my fish finder/gps units on my boat and I cannot decide what to get. I really like the lakemaster+humminbird+minn kota (for the trolling option, seems like a dream) the only thing is lakemaster does not have any of my primary lakes on it. I am not sure how successful this combination would be without the lakemaster chip. I know you can do recorded paths but don't really know how that would compare to following depth lines. Also, on the lowrance you have the scroll back which seems handy plus I really like the touchscreen. I want a large display on the helm and a smaller one on the bow and I have a budget of ~4K. Looking for experience and some help.
