I had a Leupold RXIV 1000yd rangefinder with the TBR but not the newer DNA mode. I had trouble with it last year ranging in very cold weather past 400yds on game. I always had trouble past 450-500yds on game with it. I did some saving and trading and just got a Leica rangefinding binocular the Geovid HD-B. So far myself and everyone I've showed it to just says wow. I have ranged deer out to 900yds and a hunting shack at 2040. Everything I've ranged has given instant readings. Using the Leupold side by side I couldn't read a brick silo at 730yds with the Leupold and the Leica easily ranged it instantly. It is extremely expensive but combines very good binoculars with one of the best rangefinders on the market. I would definitely recommend it as of now. I just got it so haven't had it in cold weather yet.
