To add to Rob's post, I have heard that when looking at binoculars you want to have the objective lense to be 4-5 times the magnification. So like 8x32 or 8x40 is best.(or 10x40, 10x50) I had a real old pair that was 12x25 and it was like trying to find a needle in a haystack in the woods. Keep that in mind when buying as well.
