I'm not one to argue and look for battles and opinions but let me state something...(Only my opinion)

If you are a bowhunter you may do one of the following:

1) Pace off some trees and have an idea of range in your area..
2) Hope for the best and use your instincts (and your fast bow) to make its mark
3) You only take shots at 20 yards so you have no worries
4) You're afraid range finders will cause movement that could destroy your hunt.
4) You hunt with a range finder and use percision in your shots and know how to handle a range finder based on the situation (relaxed deer, or the moment is too fast to use one)

Buy a bowtech 82nd, Hoyt Katera, or Matthews (DXT or whatever is fastest)..
Bottem line is ...archery equipment throws an arrow out to its prey........and their is alwaystrajectory!

You shoot all summer in the happy world and know your bow inside and out...

Important note: Do you ever ask yourself at full draw if the deer is 24 or 29 yards?

If you do... and release the arrow you're opening up a window of "some" variation on your shot placement..This variation could be a 2 inch "sway" from drilling the lungs or hitting the dead spot high in the back below the spine...or some other bad shot...

My Opinion...Tuck a range finder tight around your neck....learn your trees and woods with it...just in case you can't mark the deer with it.....depending on the situtation.....

As the deer enters... get yours hands on the range finder...read the situtation...if 32-36 yards is all you got....mark the deer and make it happen...by then you will know your sights....

Have confidence in your equipment and plan ahead...you can use a RF on deer in close...you have to be confident...Remember...a slight mis-judgment could cause your arrow to fly just outside of the zone...When you stack up nerves, the moment, etc...its all up in the air...

Picture the trajectory and use a RF to get your arrow into the "hair" you're aiming at...

And remember...when you mark the deer...grab your release...and reach full draw...now you're confident...you feel like you're back home on the target....it is times like this when you will realize 30-40 yards is nothing....and open field broadside shots at 48 yards are nothing....hold firm...and do what you do on the 3D range....

WOW...long post but absorb it
