I currently have the Navionics Platinum card in my Helix 12 unit. I'm interested in trying out the LakeMaster Plus after being in a boat using LakeMaster charts and know you can download a particular lake on to an SD card. If I decide to get the entire mid south card do I get any credit for the lake I downloaded, any discount? I read on one of the threads you could try the LakeMaster before purchasing but wasn't for sure how to go about this. Thanks, hope I made sense.
I fish Lake Conroe mostly but we will be fishing Sam Rayburn some for my sons high school tournaments and wondering what most people prefer, Navionics or LakeMaster, especially for Rayburn.
