A bow sight is a carefully mounted device that is placed on the riser of a bow to improve aiming accuracy. It is similar in function to the bead at the end of the barrel on a shotgun. While its use is not necessary to successfully fire a bow, it does make aiming exceedingly easier. This is especially true when firing at long ranges where accuracy is key. Consequently, almost all compound bows are currently fitted with various kinds of sights.
Fixed-Pin
According to Bow Hunting, fixed bow sights are the most popular types of sights. They allow a good range of flexibility because the various pins in the sight can be rearranged in order to best suit the current firing range. Multiple pins are found in these sights and each can be set for a different distance, eliminating the need for constantly changing sights depending on the situation. Because of their simple design, fixed pin sights are constructed with few moving parts and boast a sturdy design.
Crosshair
The function and design of crosshair sights are fairly similar to pins sights, notes Bow Hunting. They consist of a sight with multiple lines that can be aimed at different intersects in accordance with the firing distance. This design allows the shooter to prevent the bow from moving left or right, while also firing in between pin sights.
Pendulum
According to Bow Hunting, pendulum sights are specifically designed for use by a tree stand hunter. They consist of a single horizontal crosswire or pin that pivots on a hinge, giving it a pendulum design. This mechanism rises as the hunter aims downward at a target close to the tree base. As the shooter aims at a target farther away from the tree, the sight will conversely drop. The pendulum sight allows for an aiming point of about 30 to 35 yards out. The device is no longer effective when utilized beyond this point. As a result, many pendulum devices come equipped with fixed-pin sights as well to allow the shooter the ability to aim at longer distances.
