Was reading an article in one of the bowhunting magazines I get about rangefinders. Apparently the laser beam they project does not always come out straight and the object you are ranging may not be what your reading is coming off of. The article said before the season you should figure where your beam comes out so you know where to aim it while hunting. The author said he has a range finder that the beam comes out of the lower left hand corner and he has to adjust it accordingly when using it. My question is how do you tell where the beam is coming out? I can't figure out how to do this? Can anyone help?
