ok, I went down to the lake a little bit ago and found some ducks on the water I would guess about 200 yards out. I didn't have my rangefinder with me and probably wouldn't have been able to use it in the dark on the water anyway. I tried not to move the tripod taking the filter on and off, but the frames are close.
I put the 3x magnifier on the PVS-14 and took some comparision pictures with and without the Wilcox amber filter. It actually is better contrast at least on the water to me.
