Best cartography cards for Isnhore

Saltwater Inshore Discussion
1

I have a humminbird 597ci HD with Down Imaging. Im looking to upgrade the charting and cartography information to give me more of a look in the creeks/rivers and a little bit off shore (5 miles or so). What do you all recommend as the best card to use for navigating inshore with a little more help?

Thanks in advance!

It typically shows most contour lines up the 4 main rivers. Once you get shallow and in the smaller creeks it’s up to you.
