So got a new to me hds 12 gen 2 touch.I bought the navionics hot maps platinum its ok.Also got the cmap lake insight hd sucks bad.Looking for the best card for use in this graph.Accurate contours would be nice.Navionics best so far but was on geneva and contours are way off from what it says on the graph.Funny my hds gen 2 non touch 8 has alot better built in maps then both these cards.

Best mapping card

I run both and find the two different SD cards will vary by body of water. Good example is Petenwell Flowage Lakemaster and Navionics are very different. Cornell Flowage is even worse. I have two slots and run both and first time on the water will pick the best option.
Good Luck
