I am wanting to buy a lake master chip for my hummingbird 1198 and my 858. My question is would the great plains chip version 4.0 have Bull Shoals lake I mean the whole lake since most of it is in Arkansas. Does it also include Stockton, LOZ, Truman and Pomme. I can't get a complete lake list I have been trying for 2 days, every time I find a site with the list it won't download to my computer. Any other insight you could give would be appreciated. We mainly walleye fish but do some crappie fishing to. Thanks in advance. Ed
