Yes I have. I've been next to the best scopes on the market and a lot in between. Once youturn them up the detail goes away. The op was talking about detail on coal bucks not sure of the distance or lighting conditions But for field judging they just are not that good lots of mirage mid day and very dark in low light. In perfect conditions all spotters are usable. A guy with the list of rifle scopes this guy has will not be happy with the viper line and for the cost of the razor the meopta and kowas will be better.Have you used the new 2018 viper hd line, or are you just writing them off for fun?
