I took my Bushnell ConX out for a stroll and I was zapping trees at 1371 yards and a shed at 1677 yards, It was hitting the shed 10 out of 10, Things under 1200 yards were lightening quick and anything further took less than half a second, It was getting Sheep at 857 yards, But It did struggle on a black horse at around 1300 yards But that was due to Hand Shake, Under 450 yards I was able to Guess most distances with a couple of yards that I then checked with the ConX, On the whole I would say that it is the Best LRF I have used so far.
I was using it on a windy sunny day with changing light conditions so I am impressed with how it performs, 1677 yards was the furthest Target I could range because the wasn't anything else further out so I never got to push it to the Magic 1760 and beyond,
hope this helps.
John.
