Why Cam Timing Dictates Compound Arrow Flight
For competitive 50-meter compound archers, synchronization between the top and bottom cam draw stops is non-negotiable. Even a half-twist discrepancy in the control cable causes the stops to hit unevenly, producing vertical nock travel and erratic groupings.
1. Draw Board Synchronization Inspection
Mount the bow onto a draw board with an inline winch. Slowly bring the string to full draw while observing both module draw stops. Both stops must make contact with the control cables simultaneously at the exact fraction of a millimeter.
2. Cable Twist Adjustments
If the top cam hits before the bottom cam, add a half twist to the top control cable or remove a half twist from the bottom. Re-verify until solid wall feel is achieved on both stops.
3. Paper Tuning Verification
Shoot a bare shaft through butcher paper at 3 meters and 6 meters. A bullet-hole tear indicates optimal vertical and horizontal launch dynamics.
