I just bought the Bird 598, and need to buy map chips for Wisconsin and Minnesota. Navionics Hotmaps Premium has the lakes I am interested in and so does Lakemaster. Navionics is $125 for everything and with Lakemaster I would have to buy two chips totaling about $200. I am wondering which has the better/more accurate maps? At this point I do not have Ipilot, but may upgrade in a few years. Any help would be greatly appreciated!
