I would reach out to sig and ask what the operating temp is for the 8k. I’m gonna guess that it’s gonna be lower than 15-25 degrees, but if it’s supposed to be able to operate in those temps I would send it in.
Thank you I will!!
Super helpful thank you!
That mirrors my experience with Sig rangefinders. I really would like to get their range finding binoculars but I have trust issues with their electronics in the cold. It would be crazy nice if the electronics worked all of the time because being able to glass, range, and get a dope all in one step would sure expedite the hunting process. I hope you figure a solution out.Just got a Kilo3k for Christmas. Played around with it at the house and setup the ballistics which seems to line up well as long as you don’t use the onboard temp sensor.
Went out for a coyote hunt this morning and had it stowed in the front zipper pocket of my AGC bino harness. Temp was 15-20°.
Setup my stand and went to get a few ranges before starting my calling and I couldn’t even get the sagebrush at 20yds! Noticed it said the battery life was at 50% on the new battery too. Tried scan mode, tried XR, first, last, best modes and still nothing. So I put it back in my bino pack and was back to old school mental ranging. Luckily it was only coyote hunting with a max point blank of 200yds
Well, after sitting there with my pack in the sun I picked it back up and was able to get some hits on ranges out to 500yds but still not the close stuff. I put it under my armpit for awhile to warm it up and it went back to ranging just fine!
Contacted customer service about the issue and this is the response;
Most likely the batteries are the issue. We have found the lithium batteries don’t work well below 50 degrees. We recommend alkaline batteries when possible, they are hard to come by.
Google doesn’t even hit for alkaline CR2 batteries and I was under the impression lithium is better in the cold anyways???
I was thinking of trying some hot hands pouches in the pocket with it.
The hand warmer idea is actually pretty ingenious! I wonder if it would cause any fogging issues?
Good work on your experiment. My Leupold rangefinders all work fine in cold weather but I have trust issues with their displays fading away over time or I’d consider the BX-4 range finding binos. I wonder how other brands would fare with the same test? I’ll try it with my leupolds when I get home later. Thanks for your test!
My experience is the same, I’ve put my razor 4Kgb at -6ish for 2 days, and had good ranging out past 1200. If I remember correctly I was able to get around 2k(with a few tries). This was with the same battery I hunted with in the fall.
Yeah that’s been my go to.. It is super solid couldn’t be happier with it Ryan spent an hour on the phone with me to talk me through features. I think it’s the best optic vortex makes just my opinion!
