point of impact changing with change in light
I have a cobra bow sight that is driving me nuts. It seems to change the point of impact about 3" to the right @20 yds when the light is low. My sense is its an optical illusion caused by the additional light that comes through when there is significantly more light out. Is it me or the bow sight? I've contemplated purchasing a Spot Hog or other sight that contains a vertical wire. It seem that the additional light coming through the fibre optics would not change the point of impact if you were relying on the wire. Thanks in advance.
