At the same time I didn't buy these to lase birds. I don't think anyone is trying to shoot wallet groups with their Vectors. They bought them to lase targets and big game.I agree with you that on the ground it is very difficult to understand whether it is the distance to the ground or to the bird. The best way to understand the rangefinder's capabilities is to measure a bird sitting on wires at a distance of 500-1000 m.
I'm going to stop responding to you because I think you're kind of a doofus
