This. I have never found any that are good.
Print one of these out:

Put it up in failing light at 25 yards (depending on size you print) and look at them with your binoculars. it is a good way to see real differences in resolution.
Thanks I was wondering if there was a pattern availlable.
It's easy to tell the difference between bad binoculars and good ones but when they are both trending towards good it gets harder and harder.
