If memory serves me correctly, back in the day, the other brands had you upload your data. Then they sent you a lake map. they made the maps out of data people collected. One of the reasons I went with LakeMaster. Plus I have lots of experience using other Johnson Outdoors products. I really like how Johnson Products link products' to work as one. I spend less time working my electronics and more time fishing.
When i pre-fish for a tournament, the first day is mapping and hunting for cover/structure. I don't even drop a line. I need to find fish, and where they are going, coming from. Knowing their routes helps when teh bite stops and the fish move.
