They say “Less is More” that could certainly be said of the ED-PRS GenII 4-20×52 scope. Earlier this year, I reviewed Discovery Optics new GenII revision of their ED-PRS 5-25×56 scope. The GenII EP-PRS boasted improved optical clarity by using Japanese ED glass. So, why would they make a 20x scope when they already offered a 25x? And why would you want to buy one?
The 20x version appears nearly identical to the 25x. In terms of performance, the 20x has a 4x magnification factor which means in theory it should provide slightly a sharper and brighter image when set to the same power numbers as the 25x. In my testing, the differences were too subtle for me to see. But what I could clearly see is that the 20x is slightly shorter, slightly lighter, and slightly cheaper than the 25x.
Moreover, most hunters and target shooters don’t typically shoot a 5-25x scope at its maximum 25x; preferring a setting of about 12x or 16x to improve clarity and brightness. A 20x scope is able to be used at 12-18x. Let me again remind you that the 20x is slightly shorter, slightly lighter, and slightly cheaper than the 25x. It all starts to make more practical sense.
