I am looking at upgrading to a new sonar this year and am curious of any major differences between the humminbird ice helix 5 and the humminbird 688ci. They both seem to do about the same thing as far as I can see. I would like to know if the 688ci is worth the extra $100 or so. Any help would be appreciated.
