has been talked about before im sure, but need help deciding on a rangefinder. sent back my arc 1000, was terrible, now need a new one. cant decide on the vortex ranger, or maybe stepping up to a swaro? I need it to range trees at 800 yards, and have the angle compensator. I know the swaro or leica, zeiss don't have that, so what are your thoughts on the ranger 1000? consistent readings of 7-800 yards, one time button push?
