Hey mate,
For $1k you can get the Garmin 70DV. What I liked about it, touch screen, and ONE transducer. Some other brands you need different components for it to work. Lowrance for structure needs another transducer etc.
Good thing about the Humminbird, it is all built into the ONE transducer too. I think Humminbird released a fairly new one 7" around $1300 I think with it all.
