nothing like finding out someone has bullet launcher pointed your way,kinda just makes me mad too.i never could use the old stereo type range finders,just way too much parallax for my eyes.the old military optics really sucked bad but with todays technology its alot more precise and not so much hope and pray.you ever look through the big navy ship binos?what i wouldnt give for some to use as a spotting scope but then they weigh close to 150 lbs
