Second update:
Some info- where I am right now I can range out to a bit past 1,300 yards. Pretty much continuous from 900-1,340’ish. Also from 0-500’ish. Not much between 500-900 right here.
Negative 10-12° F last night. Somewhere around 0° this morning when checked. Both RF’s showed low batteries. The Revic ranged out past 1,300 yards without issues. I could only get 500’ish out of the Sig. Put a brand new battery from the house in the Sig-
No change. And interestingly, even with a brand new battery, the Sig is reading half battery life-
Then put the dead battery from the Sig in the Revic, the Revic ranged past 1,300 without problems.
When it comes to cold soaked performance, there’s a lot of things stated that just don’t hold up when checked. For instance- “the difference is in a cold battery, put a fresh battery in and it’ll work”. Sometimes that is it, and yes cold will run a battery down faster. However, there ARE differences in the RF’s themselves that enable one rangefinder to work in cold much better than another regardless of battery warmth.
