I am always astounded to hear of Leupolds that go blank the instant the sun hits the horizon. Especially since I have tested a bunch of scopes using optical charts after dark with the only light a 100-watt bulb 25 yards from the target. My tests with 3-9x Swarovskis AV's and Leupold VX-III's (among others) have never shown this amazing characteristic.
Of course a lot of people who say Leupolds go black don't specify the model number, or whether it was was Uncle Harold's 4x28 from 1969 that was repeatedly cleaned with his shirt-tail for several decades. But here we are discussing a new VX-III.
