Hey guys I have a Hummingbird 999ci HD SI on my G3 Jon I also have a Minn Kota Power drive V2 that I plan on hooking up to the Hummingbird once I get the $$$ for I-pilot. I am gonna order some lake maps of some sort and didn't know which I should order. The two I know of and am trying to decide between is Lake Master and Navionics. Didn't know what the pros and con's where of each. I like in Ky and fish in Ky pretty much all the time. I fish a lake called Cave Run lake in Morehead Ky. I usually fish the back waters feeding the lake more than anything. Kind thinking it's not gonna have anything on the back waters but if one of these two options does that would be a huge huge plus! Thanks in advance for the input guys!
