Love mine. We tested it versus the sig kilo 2200 and it smoked it in speed, consistency, and definitely in max range. When it got foggy they both didn’t do so hot to past 200 yards but as the fog lifted the 4K was hitting the 400 yard mark sooner then the sig. My max range I hit was mid 3,000 yards. Anything under 1,000 from coyotes to bushes to cows it hits consistently and quick. 1400 it starts having issues picking up animals so I switch to trees or boulders. Past 1400 until about 2800 it’s pretty consistent on trees and buildings and rocks. My 3400 hit, and we got it multiple times, was a big tower/building/thing with metal and dishes and panels all over. And I’ve never used a tripod, always free standing or resting against a tree.
