Does anyone know where to find the data cards for the entire KY lake for the 188C sounder? Most places are out of stock and I can't seem to find one anywhere I have the lake from the dam south to Blood River but that is where it cuts off, I'm trying to find the Fishing Hotspots because it has the depth Contours and marker bouys for running the channel. I you may have one and don't need it let me know, if you know somewhere that still has stock please let me know.
