Do not misunderstand, some hunters will have a realistic use for a range finder. I was just providing food for thought in case " jsasker" does not. Only he knows in the end.

As for establishing (approximating) distance in the brush, being I do not have a realistic need for a range finder, and I do not carry a measuring tape in the field, I match my (range) measuring method to that which I find more convenient to use in the field.....pacing. E.g., 25 paces on the range - 25 paces in the field. With my bows, a few inches one way or another will not make a difference.

I only use one " daytime" pin set at 25-paces, and one late " low-light" pin set at 12 paces. A shooter that uses multiple pins for multiple distance settings might find it easier to establish the distance to various spots for the corresponding pin by using a range finder.
