I just purchased a used rig and it has a Lowrance Eagle Z6000 on it. Sometimes it works and sometimes it doesn't. Half the time it won't respond to the codes I try to punch in that are in the owners manual.

I don't know anything about these things so my question is should I try to get this repaired or buy a new one?

Years ago I used a Humminbird Super 60 portable outfit that was effective and simple.

Simple is what I need since I'm a speed bump on the fish finder info super highway.

Thanks.
