Hi Everyone

Question is , I have tried to paper tune my hunting compound bow and from 6 feet I get a Nock left and from 10 yards I get a nock Right totally the opposite ?? . If following the regular procedures for tuning I would have to contradict everything to fix the issue.Every web page I look at indicates a different solution.Has anyone ever experienced this before and if so how did you deal with it?

Sounds as if you don't have a consistent grip. You may be torqueig the bow differently each time you shoot. I can get a right or left if I don't shoot with good form. Maybe you could get with nuts & bolts on good form. I'm not saying you don't have good form it just sounds that way. Also do a search on the walk back tune. IMO this is better than paper! Hope this helps

Welcome to ArcheryTalk Rob1234:

Well, it could be....
but, then, it might be....
on the other hand, it may be.....

You have to go through a process of elimination.
Paper tuning is a good check after you have looked into
several other things first.

Let's go through bow tuning in order.

1) Confirm that the 2nd axis of your sight (bubble level) is reading correctly

2) Confirm that the 3rd axis of your sight is adjusted correctly

3) Confirm that the cam(s) are timed correctly

4) Convert one of your arrows into a bareshaft...
Setup up a bullseye at your shoulder height
Fire the bareshaft into the target form 10 feet away
(foam or layered...something that will preserve the angle of penetration...)
Make sure you launch the bareshaft from a level starting position


Look at the angle of the bareshaft stuck in the target...
If the nock is low, raise the nocking point / d-loop
If the nock is high, lower the nocking point / d-loop

Keep adjusting until the bareshaft sticks into the
target bullseye perfectly level (parallel to the floor)

5) Now take a fletched shaft and spray it with foot power
(vanes and the last 6-inches of the shaft)

6) Fire the fletched shaft and look for scrape marks
on the vanes for shaft. If you have scrape marks,
then you have vane contact with the cables or the arrow rest.

If you can, adjust your cable guard for more clearance.
Maybe you need to rotate the nock just a little bit.

Repeat this experiment until you get ZERO arrow contact
with the shaft or vanes.

If you are getting shaft contact, you probably are shooting too much
draw weight for the shaft. Use OnTarget2! software to check.

7) Now, you set centershot for the arrow rest (horizontal position)
using walk back tuning.

8) Now, after all of this tuning,
now you can check with paper tuning.

If you have a strange tear, then you need to consider your bow hand grip position, and other possible form modifications.

Walk Back Tuning with Pictures...

Hang a weighted string from a nail on a target.

Stick a round sticker on the target face so that the string splits the sticker. Use your existing 20-yd pin, step back 20-yards from the target and fire at the sticker.

Don't worry about where the arrow hits.

Walk straight back to 30 yds, and using the same 20-yd pin setting,
fire an arrow at the sticker.

Repeat at 35 yds and at 40 yds, using the 20-yd pin and firing at the sticker.

If your arrows look like this pattern " / " or “\”,
then pick a direction and move your arrow rest 1/16th inch.





If the pattern gets straighter (more vertical), then that is great. Keep adjusting in that direction.





If the pattern gets more crooked, then adjust in the other direction.

Keep firing arrows and keep adjusting the arrow rest position until you get a vertical pattern of arrows.

Eventually, your arrows will hit in the target is a straight up and down line like this " | ".





LOCK down the arrow rest setting. Your centershot is perfect.



But, your vertical pattern of arrows may not be hitting the string.

The vertical pattern of arrows may be on one side of the string.
Let’s say the arrows are say 6-inches to the left of the weighted string.



Pick a direction to adjust your sight ring windage. Adjust the sight ring windage 1/16th of an inch. Repeat the test. Fire arrows at least 3 distances, and see if the vertical pattern of arrows gets closer to the string.

If the vertical pattern of arrows is getting closer to the string, then that is great. Keep adjusting in that direction. If the vertical pattern of arrows is getting farther away, then adjust in the other direction.

Eventually, you will have a vertical pattern of arrows right on top of the string.

Lock down the windage and lock down the arrow rest. Windage and center shot are now perfect.

rest assured

I can understand the product ability to give the correct height of the arrow but I'm missing how it will determine the center shot for the rest..
can you explain???
