    I have a humminbird 597ci. I was wanting to get a map card for it but my primary water fished is the Mississippi river. Do any of these cards have rivers on them, and if so, with the river changing the way it does every year, how accurate can they be? There are a couple of large lakes close I would like to explore, but I was just wondering about the river part.

    thanks,
    Jim

    Yes, the cards have the miss. river on it. However, it will only have the pools that are in your area. For instance, if you get the east card, you have the mississippi from the northern illinois border to the southern border of TN. You can look at the availability on navionics website.
