The type of electronics doesn't really matter. Just the fact that that you are finding and fishing that "something" is what matters. Even though I have an HDS unit, I still choose to watch my old flasher while actually fishing. Like AE Fishing said look at the drops, points, creek channels and sunken brush and you should kill them this time of years. If you can find that little "something" on open flats sometimes that can be a magnet to hold fish too.Usually on open water structure most of the fish will concentrate on a few smaller spots. Like a few stumps sitting along a drop off (ledge). Get your self a little hand held Garmin GPS for marking structure and your set to go. If I had to pick a debth to concentrate, try 12-15 fow.
I went to the DNR web site and pulled up the map of the lake, it looks great. I bet if you spend a little time and figure that lake out you will easily have 100+ fish days.
Since it appears to be a resonably shallow lake, I would think trolling cranks would be a good way to cover some water and explore new areas. If you want tips on trolling cranks ya got to talk to jeepguyjames, he's the local expert here.
Keep us posted on how you're doing and good luck.
