Binoculars are usually not powerful enough for spotting targets, especially small-bore.
I got a Tasco spotting scope as a result (goes up to 30X), and it's adequate for 100 yds. It hasn't had the test of moderate rain, though
Wind River makes pretty good binoculars. They replaced my El Cheapo zooms that I got for my birthday years ago.
I had to return a pair of Pentax binoculars, due to too much distortion at the edge of the field of view (forget the term for this).
One tip if you're looking at zoom optics:
Check to see how "linear" the focus stays when you zoom. In other words, if they're in focus at 7X, how much re-focusing do you have to do when you change it to 20X? How much looseness is there in the zoom meachanism? Also, how much in the eyepiece focus? The better ones should require mimimal refocusing.
