Conclusions: In bright daylight, these binoculars provided a clear view and are easy to focus. Once focused, the depth of focus was fairly generous, but refocusing from 100 yards to 20 yards had to be done one ocular at a time. At 25 yards, most testers could nearly read the entire bottom line on a Snellen eye chart in both bright and dim light. At 100 yards we could clearly read to the third line from the smallest. The binoculars are the heaviest we tested, which initially provided stability, but fatigue set in sooner, destabilizing the image.
