What is Let-Off on a Bow – Let-off on a bow refers to how much the draw weight decreases when the bowstring is fully drawn. For example, a compound bow with a 70‑pound peak draw weight and 80% let-off means the archer only holds 14 pounds at full draw.
How Let-Off Works
- Peak draw weight: The maximum force needed to pull the bowstring back.
- Cam system: Compound bows use cams that reduce holding weight at full draw.
- Let-off percentage: Expressed as a percentage (e.g., 65%, 75%, 80%).
- Result: Archers can hold the bowstring longer, improving accuracy and stability.
Benefits of Let-Off
- Reduced fatigue – Less strain when aiming.
- Improved accuracy – Easier to hold steady at full draw.
- Longer aiming time – More time to line up the shot.
- Better hunting performance – Hunters can wait for the perfect shot without tiring.
