Navionics Platinum Plus is what I run (Lowrance) . The 3D view with shading can really help out being able to read contours. I've actually found quite a few new spots in areas I've fished for years that I didn't pick up on a standard 2d contour map. Not sure if the regions have that capability? T-Boo if you have Humminbird Lake Master might be your best bet though.
