I have a 798. It is smaller, but still works great. Like was mentioned, the screen is bright and the side imaging works like the bigger units. I put mine on a ram mount so I can move it closer to my face - then I move it to face the front of the boat when I get up there - gives me one finder in front and the HB in the back. I keep it set at 75 feet each side so I can see the fish easier. If I could afford to go bigger, I'd go 1198 series. Because the 898 has a ticker on the left side, the usable screen is about the same as the 798. And the price differential isn't all that bad for 998 vs 1198.

Most of the time, I'm off to the side of any structure and I turn the screen to just look at that one side. It works awesome for this and the screen size is not an issue. For finding bait/fish in deeper water, it can't be beat!
