Navionics for wisconsin
Hello Who Farted! I use Navionics and highly recommend them as their maps are always being updated unlike Lakemaster. Go to the Navionics website https://www.navionics.com/usa and check the Chart Viewer and it will show the waters that you are interested in. Myself I have the Navionics + US/Canada card because I fish all over the country and Canada. Before I fish a certain body of water I download the most recent data to my card giving me awesome mapping. I also use the Navionics mobile app for my phone. For $10 you cannot go wrong. Tight Lines!
Check Craigslist for chips. They run about $75 or less.
What I really liked about the lakemaster chips was the details provided. If you wanted to know where you were in relationship to landmarks all you had to do was move the cursor to shore and change the range. The street detail was very useful to me.
