The reason that I shoot I single pin is that I'm left eye dominant and shoot righthanded so it helps my focus a lot with only one pin. Also I never have to worry about using the wrong pin. I practice shooting different ranges without moving the pin so I know how much to hold over if I don't have time to move the sight. Works for me.Maybe Im a dumb xxx but I dont get the slider idea. I know it nice just to look at one pin but everytime the animal moves you have to move to adjust your single pin to the yardage? Why? Wouldn't a fixed pin sight make for sense? What am I missing?......BTW I shoot a cam hanes spott hogg 7pin wrap.
