When I shot the Phantom back a week or so ago, first dot was 10-30 yards. Second dot was 35-45. I have no idea what the third dot would be, 50 I guess.
It is simple, under 35-yards, I just hold dead on, a tad high or a tad low depending on the distance. 35-45, second dot, same deal.
My shots so far have 32, 31 and 22. All have been dead solid perfect for two deer and a turkey.
