There are paper versions of the Reel Bottom map. I like them better than the whiffer maps because the whiffer maps do not say exactly where on the structure their GPS points are and they only take them two digits past the decimal. The Reel Bottom paper maps can be a bit of information overload but they are nice. The other negative is that you have to buy 4 maps if you want up close detail of the entire lake, complete with GPS points. Each map has a map of the entire lake on one side and a smaller portion with GPS points on the other.
Comparing the whiffer to the Reel Bottom map, I am amazed at how acurate the tops of the structure are on the the whiffer map. Having both, I can say I do use the Reel Bottom paper version more than the Whiffer but the Whiffer is a very good map.
