Has anybody with this card been on Watts Bar yet?  I purchased one last week.  Fished Chickamauga on Friday with no issues.  Watts Bar on Saturday was a different story.  The chart seemed to be off by at least 200-300 feet or so.  It was showing my position to be on shore by a good bit in the backs of several pockets.  Main lake points and ledges were off as well.  I contacted Humminbird today and they had no other reports.
