I just got one of the LakeMaster cards, It don't have the Big 4, it does have Pickwick and so far what little I have used it, I like it but I am not ready to say I like it better than the Navionics. Now being fair to the Lakemaster card, I have never used anything but Navionics and that is what I have grown to like, but I wanted to try the LM because someday I might be able to add the iPilot link to use with the HB and the Terrova
