a beam of 10.8" tall by 54" wide at 1000 yards.
My apologies, I was thinking the vertical dispersion was .5 mil and would be 18" at 1000 yds. I knew the horizontal dispersion was quite a bit more than the vertical though.
, that being said; I was worried about the horizontal. My thoughts being that a prarie dog is only about 4" wide Maximum. In my mind, there's a good chance that the nearly 5 foot wide beam would catch grass on either side of the dog that is closer or further than the dog itself. Much more area to catch and bounce back a reading outside and both sides of the dog, especially on relatively flat ground.........The beam on both sides of the dog would still "be out there searching" for something.? What are your thoughts on that?
I've tried the Leica's on wooden telephone pole tops against the skyline. It was tough to get consistant readings much beyond 800 yds, even on sandbags. Of course, the pole is more vertical than horizontal, so again, in my mind; I am thinking that most of the beam is in fact missing the pole and shooting past it out into space. And, the pole is round so it's not reflecting much back anyway, just as a chuck or dog is round.
Would like to hear your thoughts on this.
I'll get to see the Vectronix in action side/side to a Swarovski and my Leica 1600 this fall, excited to see the results.
