My chip covers both those lakes, like I mentioned I didn't see that it was any better. My buddy is a semi pro bass angler and last year he won a 21ft boat with a 200 hp Yamaha on it all decked out with electronics and it came with a 898 bird and he had the different individual chips, I don't see that big of a difference but they were lakes in the NE. But if you only fish a few specific lakes those chips are supposed to be way more detailed. I just did a update which now it's in 1ft contours. which is only a few hundred acres, small enough that it's a electric motor lake only. This chip is awsome it shows the SLR from start to the ocean all of LakeO and to like Port Clinton on Erie on and on it has 118 lakes on it and I found it to be dang close with the depth charts, even little lakes such as Swartswood in NJ.

I fish a lot of different places so I bought the premium chip of the north east. This is why I can't make up my mind! lol To me it is between the Hummingbird Lakemaster and the Navionics Platinum+ BUT I don't know what one to choose!
