Greg. I don't know how to use a rangefinder in a stalking or still hunting situation. I would guess the answer would be to move when the game is looking the other way. Kinda hard to do if there's a herd around the target animal, huh?

I used to have one of those old kind of rangefinders where you dial the knob until the two images are lined up, but it never worked worth a flip. Didn't need it anyway. You see, I spent about 6 years working as an instrument man on a land surveying crew, shoot 3D all year long and go stump shooting. I know how to judge yardage and work on it consistently to keep the skill fresh.

Anyone with good binocular vision can learn how to judge yardage if they want to.
