Well i use a rifle scope, 2 of them in fact. I have a 1.5x6 on my Phoenix and a 4x on Miss Vixen![8D]Never have had any trouble in 3 years. I am going to buy a Excal Lumizone, so i can use it fer 3-D shoots. Its setup from 10 to 50 yds. that will work well fer my intended use. When i hunt i just sight in couple inches high at 20 or 25 yds. Then just put the xhairs on top of back fer 35 yds. thats my max hunting range.[]
