We have a 4 point on one side rule in Northern Missouri. At 15 minutes before sunrise and 15 minutes past sundown, the only scopes that work are the Zeiss 3x10 and Nikon 3X12X50mm OL. Can't afford a Swarovski....I understand they work in low light too. The Zeiss works for 10 minutes longer......past 30 minutes! ...same price as the Leupolds which just don't cut the mustard.
