My Eagle developed a mind of its own and only worked about half the time when I started fishing this year so I decided to buy a new unit. After much research and a tremendous amount of confusion I finally decided on a Humminbird 597 ci HD DI. The down imaging is amazing and the huge variety of screen views and split screens are really useful. I am still a beginner and can't imagine what I will be able to see after a little more practice.
I wanted to post this opinion because of all the differing reviews I read while doing research. Every unit I considered had about as many bad user reviews as good ones. I finally decided there was a lot of user error in installing and using fish finders. In short, I am extremely happy with the 597 ci HD DI
