|Let-off is the amount of mechanical relaxation your bow achieves at full-draw (as a percentage of the peak draw weight). Unlike a traditional recurve or longbow, which reaches its peak weight at full draw, a compound bow reaches its peak weight about half-way back and then becomes easier to pull/hold as you reach full draw.
Today it is common for bows to have let-off in excess of 75%. A bow with a 70 lb. peak draw weight and 80% let-off will require the shooter to hold back only 14 lb. once the bow reaches full draw. Holding back such a small amount of weight, the shooter has the luxury to take more time aiming and releasing the arrow. Of course, some argue that you can have too much of a good thing. Some would say that a bow can have too much let-off, making the bow feel "sloppy" at full draw -and perhaps that's technically true. However, the average archer will find the mid to high let-off bow to be far more comfortable to shoot.
This is ultimately a matter of personal choice, but the high let-off bow is the overwhelming favorite throughout the compound bow market. With that said, advanced archers and back-tension shooters often prefer a little less let-off. So this isn't a right or wrong decision. If you would like to read more about the concept, please visit our Compound Bow Selection Guide. If the bow on this page has an option for more than one let-off setting, the drop-down box here will show the available choices. Please select the let-off you prefer, and our pro-shop will gladly adjust the bow for you. If a bow only has one let-off setting (more common today), then just the one standard let-off setting will be shown.
