I use the MapCreate 6 CD set for my Lowrance. I basically make my own chip using the chip reader/writer that comes with it. It shows all the area rivers, with chanel markers and obstructions like wrecks and such, and has just about every creek name, even allot of the really small ones, but it doesn't show depth or contour lines except on the big lakes like Buggs and Gaston.

But one handy thing is I can take my chip out at the end of the day and upload all my waypoints I've made onto the computer. So if anything ever happens to my chip I can still download all my stuff onto a new one.
