I am going to pick up a chart recorder that uses one of these SD cards over the winter. I get mixed messages when I search to see which might be better. The one plus that may push me to Lake Master is that you can get a card that includes both Nebraska and Iowa. It looks like I would have to buy two of the Navionics because the states are in different regions.

I have two questions. The first one is about the Navionics Gold. It it true that it only shows coastal areas?

The secnond is about LakeMaster. Does anybody us it? Would you recommend it?

Any input would be appreciated.
