Revic BLR 10b vs Sig Kilo 10k

I've never had any issues with any of my 3k, I have several and have used them in well below 0 many times. I'm usually wearing them in a bino harness and in those Temps usually have a large puffy coat over everything, it must be insulated a bit obviously by that. When 20 degrees or warmer I don't usually have a big puffy over everything and have never noticed any issues... I haven't used my gen 2 10k in anything colder than 28 degrees, but in just a bino harness over my smaller puffy there haven't been any issues. Are lots of other people having issues with the Sig rangefinding binos in cooler temps??

Just an update, since I was also curious after hearing about some test where the sig rangefinders don't work in cooler Temps. I was hunting this weekend and made it a point to wear my bino harness over the top of all my layers, mostly out of curiosity. The first day we walked in at 19 degrees and 35-45 mph sustained winds, all day long I kept ranging and didn't have any issues. We were out in "the sticks" all day. The second day it was exactly 0° but with zero wind, again we both had zero issues ranging with our sig binos. We were both running the gen 2 10k. Seemed to work just fine down to zero degrees, maybe my battery had better CCA than whoever was mentioned before that "tested" them in a fridge or freezer or whatever it was. Like I said before too, I've used all 3 sets of my 3k binos much colder than that without issues but never thought about whether it was inside my jacket or not... so I was curious.

Just an FYI, $1000 off Revic BLR10b binos, no back order!
