I finally upgraded and got a Lowrance Elite 7. I have to say the manual is good for starting a fire and that is about it. First time I went to Fork and GPS worked great showing contours lines. Yesterday and went to Lavon and everything looked fine leaving ramp. Then it lost satellite and while I did get the signal back I never saw contour lines again. Also on Fork it displayed the lake name but not on Lavon. Do I need to buy a map card to see contour lines?
