Have Paper Tuner Will Travel

This tear indicates a perfect tune for my Compound bow shot with a release aid. I see the best groups at 50 yards with a slight tail high and left tear.
This image is proof that a good paper tune will allow your bow will perform at it's best. This is a group that was shot from 40 yards.

There has always been a certain amount of hype and mystery surrounding the paper tuner. I will attempt to explain it as well as simplify it in this post. But first you need to know what the arrow is doing when it's released as well as in flight. This is a link to that will give you an idea of what is happening after the arrow is released.http://208.81.178.138/cms/content/video-oscillation-test




You are now asking yourself how in the world did those aluminum arrows hold up for so long. I have searched for an old video that Easton and PSE put out about 12 or 15 years ago that contained several camera angles and super (and I do mean super) slow motion.




OK, back to tuning. The paper that you are shooting through actually indicates exactly what the arrow is doing at a given distance. As you can see from the video, the arrow will bend several times in the first 15-20 feet of flight.


I am going to save you from an awful lot of shooting at paper by offering up this tip. Measure 4 feet out from you target and place the paper there. Next, measure 6 feet out from the paper and put a mark down there. I found that after testing the best tuned bow and arrow combination I have ever had that it punched a perfect hole at 6 feet every time.



Let me say this, just because it will punch a good hole doesn't mean that it is tuned. During the 2 cam days of yonder, I would set up a bow to shoot slightly tail high (only a 1/4") to obtain a good starting point. This was shooting 2312's with the old uninock. Normally it was just right.



It takes some effort to shoot 10-12 perfect holes in a sheet of paper. You have to grip the bow the same every time as well as make a good smooth release. After achieving this goal you will need to shoot every arrow that you intend to use with this setup to ensure consistency.



One of the best publications on tuning ever written is here
http://www.willowcreekarchery.com/Easton-arrow-tuning_guide.pdf


I could not find it at the Easton website, I guess that they have discontinued the publication. I would save it to your desktop and you can print pages as you need them. Skip to page 7 for paper tuning.



If anyone is interested in tuning a compound using a finger release, just leave me a comment and I will respond asap.
