Referencing the 92 to 98% differences in light transmission, how does that translate into a usable data point. I have a circa 2001 VariX-III 1.75X6X32 and wondering if it's worth spending the money to replace it and how much of a gain in hunting light I can expect/
Leupold didn't change any of the designations but made significant upgrades in 2011. I have a 2012 VX-2 that is a better scope than a 2005 VX-3. They upgraded the entire lineup and VX-2's are essentially older VX-3's, but selling at VX-2 prices. Even the VX-1's essentially became older VX-2's and now have click adjustments.
