I’m going to try to learn a little bit more about my home lake this year which will mean studying maps, depths, contours, structure, etc. That being said, I’m planning on upgrading my FF to a Helix 7 with SI/GPS/etc. I’ll also be buying the lakemaster map to use on it. One question I have is, how can I go out on the lake, mark waypoints and spots and all that and then come home and view all that on my home computer to zoom, analyze, study, etc. Is there a computer program I can do that with? If so, how much does it cost and where can I purchase? thanks in advance!
