This is about finetuning (Cam-Timing)

of 2-cam bows using"Creep-Tuning". Follow our guidelines please.

  1. As preparation, adjust the cam-timing turning the limb-bolts as exactly as possible. You can give more power to the lower limb - not really necessary (1/8 to 3/16 inch).
  2. Now, adjust your sight to 20 Yards.
  3. Mark a horizontal line with adhesive tape on the butt.
  4. Draw the bow hard into the wall - this is our reference. Shoot 4 or 5 arrows on the line. Let the arrows stick on the line!
  5. Now it becomes more difficult! Creep a little into the valley before you release the arrow and shoot 4 or 5 arrows on the line. Only "good shots" count. Eliminate bad shots or release mistakes.
  6. Is the bow adjusted perfectly, all shot are sticking on the line. All is perfect and nothing to change.
  7. What is to do, if the "Creep-Shots" hit above or underneath the tape?
    NOTE: Twinsting in has a more progressive effect than untwisting. In other words, twisting in shortens more than untwisting extends the cable!
  8. Hitting above the line:
    Shorten the cables connected to the lower cam by twisting in.
    Or extend the cable connected to the upper cam by twisting out.

  9. Hitting underneath the line:
    Shorten the cables connected to the upper cam by twisting in.
    Or extend the cables connected to the lower cam by twisting out.

  10. NOTE: Only small steps - half or one full twist. Note down your changes to record the way back. Shoot again 4 or 5 arrows to verify the changings.
  11. If you need a "Super-Fine-Tuning", repeat the procedure at 45 Yards.

IMPORTANT: Control the cables for correct positioning BEFORE drawing the bow!

Plus Tip

It is even possible to time the cams in the field without a bow press. Press one cable towards the riser. This relaxes the other cable, you can now unhinge and twist it. Using a stable tension belt is more comfortable, you have both hands free.
