I got a blue Legend 2 months ago. I am still learnig how to use it. It seems accurate. I just am having a hard time learning all the features. It came with a manual and a video but I think I would learn faster if I had someone showing me. I have used the satellite tracking screen to find caches by walking in the direction that makes the coordinates move to the ones for Ground Zero. I am sure there is a better way, but I haven't figured out how to use the compass arrows.
It also came with Garmin Topomaps that I can't figure out how to download them. I would also like to do "paperless" caching, but I can't figure out how to download the waypoints. Sooo, I could use any pointers anyone can give me.
