I have a Lake Insight HD 2012 SD card to give to anyone needing one. It fits Lowrance, Simrad, and B&G units. Covers more than 5,000 lakes and rivers plus the great lakes. Chip is brand new and the price is right.
PM me if you can use it.
The South End provides useful resources and discussion forums for those that fish The South End of Lake Michigan for Salmon, Steelhead, Perch, and Bass as well as elsewhere in the Region and Chicago area.
