i have long considered the nightforce as the best alternative in europe to those that cannot afford an S&Bender. S&Bender really seem to have their own cult here in Europe however my question is with regard to one particular feature of the NXS. if i understand well the nightforce have the reticle in the 2nd focal plain and thus calibrated on one particular magnification, which i understand to be the highest right?(25x) i wanted to buy this model however i was wondering about the problem in using this reticle in warm countries because at 25x in very warm weather you will only be able to see mirage and never ending waves of mirage so at 25x its not good and if you turn down the power to 12 or 15x your reticle is now out of calibration making a very useful tool 'out of order'. Does nightforce install reticles in 1st focal plain too? any input by those that have used NXS scopes in 100degrees temperatures?
