Good Afternoon, I was just looking at Cabelas site and saw they are now preordering for the Humminbird 598C HD SI Sonar/GPS Combo. Has anyone heard much on this unit? I just purchased the 798 HD SI unit and was wondering what the difference in the two were? This is the first time I have heard of it and thought it might have been a typo on the site as it looks just like a 798. I knew it must be legit when they said it wouldn't be ready till October or so. Just curious to see if anyone had any info on this unit.

Thanks
