I’ve owned 10x42 Leica BRF’s, Zeiss Victory 8 and 10x 45’s, and currently use 8x42 HD-B Leica. None of them worked in thick fog or heavy snow. When I can’t see more than 300-400yds w/naked eye I expect to get 25-35yd readings from the LRF’s. Too much “stuff” to diffuse the beam. Happened to me the day before Thanksgiving this year. Buddies EL Range 10x42’s didn’t work either.
None of the above have ever given me a problem in cold clear days. The coldest I’ve used any of them was -21f ambient while calling coyotes. They worked fine.
