Rangefinder to pair with NL Pures?

[Brado16]

Looking for a Rangefinder to pair with my Swarovski NL Pure 10x. Prior to this year, I used EL Ranges so glass and rangefinder was one unit, but the glass to me in my NLs is better than my older EL ranges and wanting to go two separate units and give it a shot. Looking at the Revic BR4, Sig Kilo5 and Sig Kilo 8k. Primarily use will be for getting an accurate range and ballistics solution but also interested in the OnX mapping capabilities the Sig offers. One of three hunts this fall will be in AK and I’m sure fog will be present at times. Any user feedback on the units I mentioned above? Pros, Cons, Ext?

I had the Br4 and the 8k. If it was for rifle use only I would have kept the br4. But being I use it for rifle and archery hunting I kept the 8k.
