I fished last april/may opening weekend for c/r,had a great trip. I plan on going back same time for the c/r smallmouth fishing. I got a list of waypoints off the net and was going to load a couple in my Lowrance . i am not experianced in the gps anyway but when I tried to find the L'anse Cruse Bay Hump for example the hump came up in the middle of the lake on Marinecruiser and depth did not look any different. Is marine cruiser datum differnet than say the Lowrances or are the coordintes I have inacurate. Just killin time right now waiting for the hard stuff to disappear anyway. Thanks for any help
