I was trying to range a 20"x30" plate at a grand in some heavy mirage with my Leica 1200 and it was not giving me a reading. I changed the battery, and got he same results. Later in the evening when the mirage disappeared, I was able to get ranges easily on the plate.
Has anyone experienced Mirage effecting there rangefinder?
