have had one for 2 season's got mine mostly for sheep and goat hunts. I have been pleased but last sept hunting ranged what might have been a B & C caribou biggest in herd of 11. I was walking parrell or diagonal to the moving group over edge of river bank. i was below from chest of bull by 3-4 feet , not significant for the arc. ranged at 29, I did not beleive it was over 20. reranged....29, nothing but sky behind bull that i could see. below his belly i could see quite a ways. I believed my range finder and shot over the bull. paced off later and it was right at 20???? not sure what happened there. I have rehecked range finder multiple times since it has been right on???? so i don't know if it was me or the range finder, it felt like a good release on my part. and had arrowed a smaller bull 4-5 days before at close to 30 yards.
