My only complaint about the Go Pro is as you stated. Here's a vid I shot Sunday. I'm casting to the point on the left, but it appears in the video as if there's no possible way I can cast that far, it seems so far away. LINK
I have it set on that setting, because I want to make sure I can pick up a lot of activity, but I need to see if there's a setting that will bring it in closer. After a few videos, it's obvious that on this setting, you can't really see the blow ups out that far anyway, so might as well change it.
