Lee- like you I struggled with this for long time. The most important thing is proper form, then bow set up, goes hand in hand. I went to get help by going to Bob Weley shooting school. Taught me and alot on here know about proper practice! Take five best arrows, stand at set range, Bob said 10 yards is good to start. Shoot the five arrows into a 8" bull, pie plate. Add up the arrows in, 5 points each. Pull the arrows, go back and shoot again. This will be four ends, with possible total of 100. When you get to 90-100 points, step back two yards and do the same perfect practice. Once there, step back another couple yards. Take your time, no rush,relax and shoot each arrow the same. Like I am sure you have heard or read about a secondary spot. Take a balloon, and/or a sticker tab. Stand again at 10 yards, shoot three good arrow's, into the target concentrating on the spot to hit. With these three arrows that grouped within and 1" of one another, measure from where they are up and down, left and right of where you was trying to hit. Now, put the balloon or sticker tab opposite of your measurements. Example, you tried like all of us to hit center of bull or heart shot. your arrows grouped (showing good form) 4" high and 6" left of where you was trying to hit. Now measure down 4" and right 6" and place balloon or sticker. This is your secondary aiming spot. Go back and shoot again. Now the trick, focus as you did on what you want to hit, in your peripheral vision see where the piont of arrow is and put it on secondary spot, shoot, should be real close to what you want to hit. This takes time to get used to, for we have seen in one plane most of our lives, but before long you will pick it up. Then shortly after that, you will not even need the secondary aiming device, will be programmed in. this takes few week's, don't get discoraged, all good things take time. once you have it, will never go away, just need brushed up. Any question's feel free to PM me.
