Quick Answer
For optimal bow performance, your bow string should be tightened to the recommended poundage, usually around 80-90% of the draw weight. This allows for a smooth draw cycle and prevents over-tightening, which can damage the bow. The ideal tension will also vary depending on the bow's make and model.
Setting the Correct Tension
To set the correct bow string tension, start by checking the manufacturer’s recommended poundage. A general rule of thumb is to tighten the string to around 80-90% of the draw weight. For example, if your bow has a draw weight of 70 pounds, you would aim to tighten the string to around 56-63 pounds. Use a bow scale to measure the tension accurately.
Tuning the Bow
Once the string is at the correct tension, it’s time to fine-tune the bow’s cam timing. Use a paper tuning method, where you shoot arrows at a target and observe the arrow’s impact point. If the arrow hits to the left, the cam is too far back, and if it hits to the right, the cam is too far forward. Make adjustments to the cam until the arrow hits the center of the target.
Final Adjustments
To confirm the bow is properly tuned, perform a walk-back tuning check. Shoot an arrow at a target, then have someone hold the bow and slowly walk the bow back to the target. Observe the arrow’s movement on the target. If the arrow moves to the left, the cam is too far back, and if it moves to the right, the cam is too far forward. Make final adjustments to the cam timing to ensure the bow is properly tuned.
