Zero lines card Louisiana guestion

[jp2]

Does Humminbird zero line card base maps have any more Louisiana lakes on it than the regular lakemaster map card? I read on a post here that if your lake is not on zero lines base map, it's way more difficult to create a countour map of that lake. Also says if you buy the card and maps not on it, Humminbird's response is, "tough". If there is over a million lakes with base maps on the card, how do you know?
