Archery sight pins are designed to provide a reference point to help the archer know where the arrow should land upon launch. Sight pins are mounted on a bracket attached to the bow's riser. When the archer nocks an arrow and pulls the bow string back to the anchor position, the sight pin is then placed on the target. This is accomplished by keeping the drawing hand fixed in place at the anchor point on the face and moving the bow into position so the sight pin is on target. The pins can be moved to compensate for elevation and windage.
Nock an arrow on the bow string and pull the string back to a full draw. Make sure the string hand is firmly anchored on the face or chin.
Place the bow's sight pin on the target and launch the arrow. Shoot at least three more arrows, making sure you are consistent with your draw, anchor, point of aim and release with each shot. Your objective is to get the arrows on the target in a group as large as your hand. It does not matter if the group is nowhere near the bull's-eye.
Adjust the sight pin elevation by loosening the retaining nut and sliding the pin up or down in its track. If the group of arrows is below the bull's-eye, lower the pin. If the group of arrows is above the bull's-eye, raise the pin. Tighten the retaining nut once the adjustment is made.
Shoot another group of three arrows and make any further elevation adjustments, if necessary. Once the elevation is set, it is time to adjust the windage, or where the arrow lands left or right of the bull's-eye.
Screw the sight pin in toward the bow's riser if the arrows are landing to the right of the bull's-eye. If the arrows land to the left, screw the sight pin out, away from the riser.
Continue to shoot groups of arrows to make final adjustments to the windage until the arrows are centered on the bull's-eye.
