Mapsource Blue Charts

[Yooperdad]

I'm looking for a recommendation regarding Mapsource Blue Charts. I have a now discontinued Garmin 182C Chart Plotter and a handheld Garmin GPSmap 76CSx. I was looking for detailed map availability and it appears that the Blue Charts are the compatible charts for these units. My 182C is great but only has spot soundings, which are OK but not very useful for locating structure.

However, I couldn't find any decent screen displays for the product and don't want to make the investment without more information. I was able to get enough detail for Lake Michigan from a free website that shows the bottom contours and gives GPS coordinates on screen here:

But would like to get the bathymetry coverage for Lake Superior.

Any recommendations?
