RE: Bushnell Yardage Pro Sport 450
I have one. I actually bought mine for golf.....and use it for bowhunting. Long ranges??? Heck....400 yds to +/- a yard or two is good enough for MY bowhunting.
They say it's not good in low light conditions. I see this NOT as a hinderance, though. If it's too dark to read my LED readout.....I have NO BUSINESS shooting, anyway.
It's a great range finder for the money. I picked mine up in 2000 or so (so, yes....it's tested) for <$150 on an internet deal.
