I used my ZEISS RFs on an antelope hunt, temps in the 90s with no issues, might be worth putting them in the fridge to cool them, range something and then hit them with a warm hair dryer to see if there’s a ballistics change. You threw out quite a generalization. Are you talking about any rf (range finder), the ZEISS model specifically, rf binoculars vs regular range finders? Does dropping them change the ballistics?
That’s not a generalization. How do you think they are gathering the environmental data to give to you?
