I just bought two rangefinders, the first one i bought was a Bushnell Scout 1000 w/ARC, could not get it to range over 671 in a clear cut, and the ARC was not close to what they say it is, I was shooting a 3D course and had a target at 35yds -18 degrees, It was telling me the adjusted yardage was 34yds, so i aimed for 34yrds and the arrow went just over the targets "wolf" back, so I readjusted for 29yrds and made a good hit, I had a few other targets that were inclined and declined and never could get a correctly adjusted yardage.
So i ended up taking it back and traded it in for the Nikon Monarch 800, have been pleased with it so far, I've only had it for a few days now, so I'm still testing it, it does not have the angle compensator on it, but it is fully waterproof and fog proof, the Bushnell was only weather resistant.
