I'm not sure if if I've ever used my Zeiss PRF in below zero temps(where the device was below zero...) but I do know that it would give much faster and farther readings in fog/snow compared to an old Leica that I used to have. But this is dated info, the Zeiss must be almost 8 years old.
Supposed to be -3F tonight so I could test it in the morning.
I do know that those lithium ion batteries work a helluva lot better in cold temps compared to the standard batteries.
I run the same PRF as Sam and have seen the same thing. I haven’t had enough issues to swap it yet, but I’m sure it’ll happen eventually.
