First off, I want to say good for you in taking more time with your equipment. Too many "bowhunters" don't take the time to properly tune a bow and shoot enough to be proficient. Welcome to the world of the tuning freak.

Mobo is right, first eyeball everything until it looks close. This will get you in the ball park. If you don't have a paper tuning jig, find a shop that does. Shooting through paper will let you know how the arrow is leaving the bow. If its correct, you will get a perfect bullet hole in the paper from 6ft. Keep in mind when you do this to pay close attention to your form and make a "perfect form" shot each time.

One you do that, its time to group tune. Shoot a good 3 shot group from about 10 yards, move back to 20. Using the same pin and same aiming point, shoot another 3 shot group. Look to see which way the group is leaning at 20. If its to the left, move the rest slightly to the right and shoot again. If they're inline with your 10 yard group, move back to 30 and do it all over again. You're basically just lining your groups up from short range to your longest comfortable range. Once you get that finished, you should be in pretty good shape. You'll find better groups and more confidence.

And, you'll outshoot your ol' man.
