Looks like after only a month my Lakemaster card is shot. New Helix 10 will not read the card. Pulled it out of the slot once. Needless to say, I'm a little ticked.
Now for my question.
I used a Navionics card over the weekend for a local lake (Lakemaster wouldn't read and it's not an HD lake). Is there anything that I can't do on a Navionics that I can do on a LakeMaster? ie. autochart, waypoints, casting rings, spotlock.....
