the top pin is for the shortest ranges and the bottom pin is for the longest range. shoot a group of arrows with your top pin. where ever your arrows hit follow them with your pin. so if you shoot a group of arrows and they all shoot low of where you had your pin move the pin down a little. after you get the vertical set, then go to the horizontal. if your arrows shoot left of where you put your pin, then move the pin a little to the left until your arrows are shooting the same as where your pin is.

remember to practice practice practice before the season starts good luck!
