I tend to glass further with my 15's 300yds out to around a mile. The futher distances give you a much better field of view to look at so you can cover a lot of ground. The point made about watching the close stuff is a good one. I take breaks and lean back and watch the hill, draw, flat, etc nearest me for a while. Inside of 300 yards there is a good chance of catching animals with your bare eyes (assuming 20/20) since you have a very wide field of view you can watch a very large area. If I know I am in a spot where I expect to see game then I will use the bino's to really pick apart the closer terrain.
