A PSE compound bow will need some minor adjustments before you put it to use. The most common adjustment needed is changing the draw length, which varies depending on your wingspan. To determine your personal draw length, measure your wingspan from the tip of your left middle finger across your chest to the tip of your right middle finger. Subtract 15 from the total and divide by 2. Change draw lengths on a PSE bow in small increments for an exact fit.

Put the bow in a bow press or relax your strings by backing out the limb bolts.
Move the string to the minus "-" post. This will decrease the draw length by a half inch.
Move the string to the plus "+" post. This will increase the draw length by a half inch.
