I have the premium 07, with the 1' contour lines. LOZ and lower truman are great, but anything up river on truman no goood. For instance they show the lake running out of water on the osage arm at the Hwy C bridge. Word is that they came during the winter months and the lake was froze over keeping them from doing a good survey of the upper ends. I have asked when they might come back to fix the problem no word yet.
