I have sword twilight hunter for the last couple of yrs. A green pin for 25 yds. a orange pin for 40. I'm 52 yrs. old so my eyes are not what they use to be. The pins seem to get blurry, and seem like there is a halo around each pin as day light decreases. There could be a problem when hunting in the evening. Anybody else with this problem, if so did you try a different site?
