Double check the Hummingbird unit you are looking at. The one you described does not have side scan. The Helix 7 with side scan is a $700 unit. As far as chips go I would recommend the Lake master for Minnesota. I have the Wisconsin Lake Master chip for my unit at the console, the color and options for the high def lake provide a lot of options for how you want to view the information. As far as Indiana goes I wouldn't spend the money on a chip. Lake Master doesn't have a lot of the reservoirs I fish in high def and the Navonics is not much better than what is comes on the Humminbird units. Personally I am partial to the Humminbird unit and I am going to purchase a Helix 7 DI/GPS for the front of the boat this week.
