im not really one of the way out there hunters but i have good success to 500 yardw with my old bushnell yardagepro 1000. it wont range deer sized targets out to 700 but it seems fine out to about 625. when i need more range i borrow a friends leica 1200. its not the very best out there but it can read coyotes out to about 900 and deer out to 1100 with +/- 5 yard accuracy. the very best ive used was a elcan marine model. it could range shorelines out to 10 miles with about a 20 yard accuracy and it could read boats out to about 1 mile with what i think is spot on accuracy
