This morning I ran a quick distance test on my Nikon Prostaff 440. Using a tripod for stability, I shot the laser at a tree ID plaque from distances of 40, 60, and 77 yards. In the field, I very rarely shoot anything over 70 yards, so this test should be very useful for my purposes. Moving forward towards the click-over point between 40 and 40.5 yards, I used a plum line from the center of the rangefinder to a point on the ground, and checked the distance using a 75' metal logger's tape. Assuming the click-over point is at 40.24, 60.24, and 77.24 yards (I don't know how good this assumption is), here are the actual distances I recorded:
Laser display (Yards) Tape distance (Yards)
Adding a click-over distance of .24 yards, my conclusion is that the 440 consistently shoots longer than the actual distance: 40 yards at 39.46 yards, 60 yards at 59.36 yards, and 77 at 76.26 yards.
Please correct me if you catch any mistakes in my thinking. Remember, this is only one test, with one instrument. Results may vary.
