RE: Rangefinder Accuracy
I've seen things on this but here's my take...
Is your shooting skill going to matter if you're off by a yard? 2 yards???
I shoot quite well but as long as I'm within 4 yards I can't differentiate if 'I was off' or if I mis-judged the yardage...
Also - if you sight your hunting rig in based on the readings off your rangerfinder I think you'd be hard pressed to find it being 'off'.
Finally - FWIW - My rangerfinder (bushnell yardage pro cheapest one I could find for 179 from cabela's) is always within 2 yards - which is close enough to me!!! (and it worked well this fall - first time user!!!)
