I'm looking to replace my old 565 up front, and there just aren't a whole lot of models left that are exclusively 2D sonar most of the more advanced models include DI which isn't compatible with the US2 on my powerdrive V2.

Now, will a DI unit hook up with the US2? I just won't have the DI feature. The next unit I get is gonna have the GPS also, so I'll do what I have to do either way

I have a limited budget also, I saw a little 398ci w/side imaging on Amazon for less that $500. Yay or nay? I imagine the screen's fairly small. Any other SI unit is out of my price range. Some good HD DI units with GPS are in my budget.

Thanks for input!
