I love mine, got a Lowrance 100 its about 8 years old and still use it alot. The newer models are even better. I think the H2O has lake map chips that you can install in to them. I would pay the little extra and get the color it makes it easier to run the channels. The only 'bad' part is the screen is hard
to see while running. If your like me you start out with the handheld and end up getting a "big screen" model for the boat and use the handheld for the truck and hunting...
