OK, fellow Illinois anglers, I need some advice for the best chip for
my Humminbird. It's a core model 999ci HD si. I've looked at the
Navionics and others and don't really like the fact that you're
linked with other states that I don't fish. How about some really
solid advice for someone who fishes Rend, Shelbyville, Bloomington
Crab Orchard, Lake of Egypt and a few others, not to mention the
south end of Lk. Michigan for some salmon, once in awhile.
Thanx for the help - Dave
