The 1946 was in yards...It was an overcast day so it was a good time to range. I was getting 1600 yards pretty consistenly...1800 yards had to try a little harder. I'm not sure what the range limit on the rangfinder is because that was the farthest I to range but I'm guessing I was at the edge. I had to be super steady and it took more than a few tries to get that reading. I did range over 1900 yards more than once though so it was not an accident!
