I’ve been looking at the new Humminbird LakeMaster chips for Minnesota, Wisconsin, and Iowa/Ill. One question I have is when it has Mississippi pool #4 and #8 listed on the Minnesota, and Wisconsin cards, does that include everything in between? 
Also on the Iowa card, How can the largest body of water in the state of Iowa (Lake Red Rock) at 19000sq acres at full pool not be included?
