The best navigational tool is your eyes, watch for the booies, the LBL side has the river channel and is the easiest way to run if its not windy. The public/shollow side is marked but you have to pay attention to the booies or you could hit something but get a map and you will see what I am saying. I run a Lowrance with a older navionics chip and it has not lied to me and I have run on Kentucky and Barkley on the flats in little channel/ditches with not problems. smbass has a HB.Last edited by Issy1 on September 15th, 2011, 12:20 am, edited 1 time in total.
