One summers evening set up a compare as it is getting dark, against a dark background at 100 yards or so. The results will be surprising, as to which scope will be the last to enable you to take a shot.

With a friend a few years ago we compared Vx3 4x 14 x 40 Luepold, IOR 56mm, Swaro PVS 50mm,, NSX 6x 22 x 50, Ziess 3 x 9 x 36, Simmons 2 x 7 x 25 and a couple of others, the winner was the little 36mm Ziess where you got at least another 5 minutes over the second placed scopes. All reticules were switch off if illuminated to get a fairer result. Nothing from S&B was included as we had nothing from them between us.

NSX is a very good scope, ret is illuminated so will allow shots in MOST circumstances depending on the reticule but I have had the center dot vanish at about 9.30pm and had to switch to using the side bars instead on NP2DD reticule. Using that scope at night given a decent lamp you wont need the illumination and when its turned up it can glare so I keep it turned down.
