Sight Physics

We were out at the range today trying to sight in our new Viper Quickset sights (a single pin sight with a slider for yardage adjustments). My wife was having trouble getting hers set. She got it pretty well sighted in, but...... Her sight was set almost as low as we could make it. The way it was she would barely be able to shoot out to 30 yards, and no way she could reach 40. By the way, she shoots a Hoyt Selena set to 42#, 25". There was a little bit of adjustment left in the actual sight mount, so we moved it all the way down to give her more adjustment with the slider.

So, we did that, then we set the slider back at the bottom (puts the sight as high as it can go), and tried again. She still nearly put it in the dirt. Played a little more, and got the same results as before. Still no way she could shoot the 40 yard target. Now we are both getting really frustrated. I start rethinking what we are doing, but we are doing it right. The higher the sight pin, the lower your arrow will hit. Finite and hard set rule. Finally it dawns on us! Why not just have her change her anchor, and move the peep up? By moving the peep up and lowering the anchor, you effectively move your entire bow down. With the bow moved down, you have to angle the bow up to see the sight pin if it was left in the same place. Therefore, you hit higher on the target. OR, you can do what we had been trying to do all along, move your sight up!! We didn't move the peep yet, but we moved her anchor and she shot a few. Now her sight is almost at the top part of the slide when she shoots the 20 yard target, giving her plenty of adjustment to allow her to hit the 50 yard easily, and maybe even he 60. She is trying to decide whether she wants to use the peep anymore, or work on using a kisser and just feeling out the consistent anchor. But that's a discussion for another day.
