of the arrow flight. Some believe that the hand with the greatest dexterity should therefore be the hand that draws and releases the string. Either eye can be used for aiming, and the less dominant eye can be trained over time to become more effective for use. To assist with this, an eye patch can be temporarily worn over the dominant eye. The hand that holds the bow is referred to as the bow hand and its arm the bow arm. The opposite hand is called the drawing hand or string hand. Terms such as bow shoulder or string elbow follow the same convention. If shooting according to eye dominance, right-eye-dominant archers shooting conventionally hold the bow with their left hand. If shooting according to hand dexterity, the archer draws the string with the hand that possesses the greatest dexterity, regardless of eye dominance. Modern form To shoot an arrow, an archer first assumes the correct stance. The body should be at or nearly perpendicular to the target and the shooting line, with the feet placed shoulder-width apart. As an archer progresses from beginner to a more advanced level other stances such as the "open stance" or the "closed stance" may be used, although many choose to stick with a "neutral stance". Each archer has a particular preference, but mostly this term indicates that the leg furthest from the shooting line is a half to a whole foot-length from the other foot, on the ground. To load, the bow is pointed toward the ground, tipped slightly clockwise of vertical (for a right handed shooter) and the shaft of the arrow is placed on the arrow rest or shelf. The back of the arrow is attached to the bowstring with the nock (a small locking groove located at the proximal end of the arrow). This step is called "nocking the arrow". Typical arrows with three vanes should be oriented such that a single vane, the "cock feather", is pointing away from the bow, to improve the clearance of the arrow as it passes the arrow rest. A compound bow is fitted with a special type of arrow rest, known as a launcher, and the arrow is usually loaded with the cock feather/vane pointed either up, or down, depending upon the type of launcher being used. The bowstring and arrow are held with three fingers, or with a mechanical arrow release. Most
