One poster stated he hunted for 40 years without this feature. I have hunted since the 1960's without it. I quickly started putting only Leupold scopes on my hunting rifles/pistols after using cheap ones for a shot time. I now have 3 VXR 3X9X40 duplex Firedot scopes on rifles replacing the old Varri-X II and VX2 Leupolds. I have not used them hunting yet but will be using them soon. I have some local hunting(pigs/exotics) coming up and an Elk hunt in Oct. I wish I had one on my trips to Africa because I was unable to see a warthog in a very dark area that had huge tusks and it would have been better on a night hunt I was part of. I hear good things about the Trijicons but do not care for the part of replacing the element. Besides I have never had a Leupold go bad and I have over 20 of them. If it isn't broke do not mess with it so I will stay with Leupold on my hunting firearms.
