Money buys quaility here just as in your other optics. The Leica's and Swarovski will range better than the Nikon or Bushnell's. Speaking from Ive used all first hand. Leica and Swarovski will range just about anything you try to range. Ranges outpast 1000 yards is not uncommon. I like the Swarovski better due to it will work better while its snowing out. Thats my only complaint of the Leica, when snowing a fair bit, is the only time it will not range 100%. Leica however will spit out the range faster than the Swarovski as its as fast as you hit the button. The swarovski you must hold down the button for a second while it reads the range while doing so keep holding on target. Want a rangefinder than will work 90% of the time or better no matter what the object is. Buy a Leica or Swarovski.
