Input:
I got this for my dad who is a boater.  I played with it extensively beforehand.  If you haven't tried IS binocs, you will be blown away.  For boating, I would have preferred a larger objective, but the price starts getting astronomical.  Plus I didn't want to go too much on magnification (typical marine binoc is 7X50).  This is a good tradeoff and a great price.
