Finally got to a place that had many different laser range finders. I and the owner of the store compared them outside the store not inside looking through the windows. Leopold, Nikon, Leica, Swor, Bushnell=no battery and Zeiss. We ranged many different things from signs to trees to buildings from 100 yards out to close to 600 yards??????????????????? They were all over the place. They were 50 yards or more different!!!! Except the Leica 1200 and the Nikon 1200 were consistently only 5 yards different at all ranges. I still do not know how close to being accurate these two are. I would have liked to compare the Bushnell 1500 pin seeker, but no battery. Now I would like to know how to buy one and know that it is accurate??? I am very discouraged. joseph PS: I am tempted to get the Nikon Monark 1200 because it was very close to the Leica, but 100$ cheeper.
