Western Oregon under dark timber and an overcast sky gets dark pretty fast. I haven't had issues with making out a head to the end of legal light with my vx3's. However the bushnell 4200's are a great scope too, maybe a little clearer. Also heavier and larger with less eye relief but built like a tank. I'm sure there are much better scopes. For those with deeper pockets, you should purchase whatever makes you the happiest. At what point diminishing returns factor in is for you to decide. For anyone that thinks I'm a moron; that's cool, wish you the best in life.
