Hi
took a new pair of Leica Bino's away for the weekend,
Friday night was overcast with a cold wind blowing not to sure of Temp but would only be in the 10 degree area,
i could not get a reading on bino's above 350-400 yards, These bino's are suppose to range up to 2700 yards, the next morning they were the same, but by 8am when it started to warm up i could get out to 1200 yards, back at camp at lunch time we could get out to 2670 yards, by then it was a clear blue sky and hot,
Sunday morning it was more of the same and could only get out to about 350 yards again, until the sun started to peek over the mountains, then we were getting over 1000 yards again.
Today i decided to put Bino's in fridge for 20 minutes to see if it was Temperature related, when i took them out they were 11 degrees C, (Bino's have a thermometer reading in display menu), i could only get a reading of 285m.
sat them on bench to slowly rise up to room Temp.
At 14degrees i could get out to 604m
At 16 degrees i got out to 1200 m.
my Question is,
Has anyone else struck this?
Anyone gone Tahr Hunting in Winter and had trouble with Rangefinders?
Have had Swarovski range finders in the past with no problem with temp affecting readings.
Have been in touch with dealer and they will be going on a plane trip back to the motherland.
