I think the best part of a range fnder is they take the guess work out of distance, as arrows and bullets drop as distance gets farther
so the better info you have the less chance for a miss/wounded animal/target
one less human error to worry about after all we are all human, and can make a mistake(guess all tools can make errors too LOl)
but for any archery hunter that likes to shoot far/take long shots,
I say there a must have item,
but if you only take short shots, then, they may not be needed at al!
still don't hurt to have one, if you can afford it!
come in handy for measuring food plots too
69x69 yrads is an acre more or less
so they have more than one tool
and many folks that golf use them too??, I don't golf so, cannot add much here, but they do sell a lot to golf folks, and not just hunters!
