I returned two Bushnell Sport 450's before getting a Nikon 440. When I received the first Bushnell I could stand at one distance (I believe it was about 25 yards) and get three different readings. I figured it was faulty so I sent it back and they shipped another one. Same thing again. So I sent them about $50 more to try the Nikon. Not only did it show the same yardage from the same spot, it showed itin 1/2 yard increments. I say you can't go wrong with the Nikon.
