I continue to learn how to use my garmin 73sv/dv more and more. Saying this, I find more things on the edge of creeks, river channels, and such I never new was there. I fish them and can see fish but am not schooled enough to know how to target them. The fish I found Friday on ledges were 10-14' and would not hit a damn thing I threw. So, I went to the grass and caught my fish. BTW, My garmin countour lines vs a navionics on my lowrance is so much better and accurate for Neely.
