I noticed Saturday that my lakemaster mapping was not even remotely close on watts bar. On chick it is pretty much spot on but yesterday I noticed it was off more than 30' feet deep in some areas of watts bar. It was impossible to navigate with it. I went into one area and the map showed the lake ending in a cove but when I got there the lake went for what looked like a mile further back. </p>
The depth was 29' on my sonar but the map showed it 14'. When I offset the lake level to match of course the rest of the lake showed up. Then when I moved a hundred yards the map said it was 16' deep but my sonar said 2' deep. I thought that maybe that area had been dredged or something but it was all jacked up all over the place </p>
Needless to say... I didn't trust running anywhere on the lake but between the navigational buoys.</p>
Anyone else ever noticed this?</p>
