Map chip difference?

[mskyfshntchr]

Looking at map chips for my Lowrance 520.

My options are the Fishing hot spots north map or the Lakemaster Minnesota map.

I do some fishing in WI and Iowa, but not a lot. I know the hot spots has more states than just MN. Other than that, what are the differences to the two maps? Is one better than the other?

Thanks.

Schweady has some pretty good info in this post.

There are allegedly differences in zoom capability. Also some lakes might be DNR vrs high resolution survey.

I have both. The Lakemaster appears to be more detailed on the high resolution lakes. The Hot Spots chip has pop up tips for certain lakes as far as what to use to catch the fish etc. in the "Hot Spots".
