Free: Contests & Raffles.
Put your old sight back on, place an arrow on the rest and measure the distance from the top of the arrow to the 20 yard pin. Then put the new sight on and do the same thing. Depending on the distance from the peep to the sight pins there may be some minor differences, but it will get you in the ball park. Will let you know how much you need to adjust the bracket or if there are other issues.Even if there are rest or fletching contact issues you should still see a change in your POI when you move the pin 1/8". If there is no change in POI then the issue is usually between the ears. Matching it up to the last sight should get you back on track and on the road to finding the issue.
