Beginner Basics: How to Fix Peep Rotation

The Beginner Basics post will provide guidance to archers new to the sport. I hope to save newcomers from some of the headaches that I experienced when starting out. Peep rotation resulting from string stretch creates one of the most common issues for beginners.

In the first few hundred shots the strings on a bow slowly stretch and settle in. As a result, the string and peep rotate. Archers will notice a smaller sight picture and it’s no longer a perfect circle. Here are a few options for dealing with peep rotation.

Twisting the D-Loop or Peep Sight

Peep Diagram

For a peep sight only slightly out of line a hunter can get away with rotating the D-loop in the opposite direction. If your peep is rotated to the left, hold the serving and push the D-loop knots to the right (Top photo). If the peep has turned slightly right,  rotate the D-loop to the left (Bottom photo). This will create a bit of torque on the string and the knots will eventually creep back to where they were before, but for a quick fix without a bow press, its a good option.

You can also directly twist the peep each time before you draw back. However, consistently twisting the same amount, especially in high pressure situations, will present challenges. I mention it because I have seen hunters that do it, so it must work for some people. But, I’ve also heard horror stories of coming to full draw on a bull with a sideways peep.

Twisting Your String

If your string reaches the point where the D-loop is sideways or backwards, take the bow back into a shop and have them add a couple twists to your string. You may still need to adjust your D-loop slightly afterwards.

For those that own a bow press just add a half twist at a time in the direction you need your peep to rotate. Adding twists to the top will have a greater impact on the peep than twisting the bottom. I prefer to add twists to strings and cables because taking twists out can cause the serving to loosen. If you need to get your peep to rotate left consider adding twists (making the peep sit completely backwards) then flipping your peep around.

Moving Strands

When twisting your strings doesn’t work try removing the peep and splitting the string with a different set of strands on each side. Most archers separate strands according to color, but it isn’t necessary. Try moving a couple strands from each side to the other, keeping the same number of strands on both sides of the peep. This becomes a bit of a guess and check game. Take your time.

A new Peep Sight

Several companies make a peep sight with tubing attached, which ties to the buss cable by a piece of surgical tubing. Or check out a peep sight aligner. The tubing pulls on the opposite side of the peep to line it up.

However, it’s not a perfect solution. The tubing will wear out over time and pulls on the peep in an upwards direction causing the peep to creep upwards. Also, the tubing can affect the speed of the bow and create torque on the string. I’ve heard customers say, “I don’t want to take any chances with peep rotation,” when explaining why they use such a peep. I used one on a Quest a few years ago and had just as many issues. Start out with no tubing, and if you can’t seem to fix the issues, attach tubing as a last resort.

Conclusion

Most of the time a little work with the D-loop will solve the problem. If it becomes a pain where you have to twist the knots every shot, take the bow into your local shop and have them twist your string or separate strands. A new peep may solve the problem but may also create others. Lastly, your peep doesn’t have to be perfectly aligned. As long as your confident you can see through it to make a kill shot, then good enough is good enough.  Thank you for reading, Stu.
