Slingshot aiming method course

The slingshot aiming method tutorial is as follows:

1, aim left and right. In the process of aiming, it is easy to master left and right aiming, and the key point of left and right aiming lies in the coincidence of three lines, as shown in the following figure:

Three lines, one is the upper rubber band, which should be shrunk into a thin line in the field of vision, the other is the lower rubber band, which should be shrunk into a thin line in the field of vision, and the third line is the tangent of the upper and lower bow edges. When aiming, by slightly adjusting the posture of the right hand (the hand holding the bullet), the two rubber bands shrink into two thin lines in the field of vision, and then the two thin lines completely coincide with the tangent of the bow head edge (the key point is to observe the relationship between the lower bow head edge and the rubber band).

Whether the three lines overlap is the most important factor affecting the left and right accuracy, and it is also the most difficult place to master, which needs to be practiced emphatically. If the line of sight is narrowed to a point in the field of vision, and the above three lines overlap, then there is no big problem in aiming left and right. You can practice shooting some slender columns or mineral water bottles to gain confidence.

2. aim up and down. It is difficult to master aiming up and down, and unlike aiming left and right to find objective indicators, it relies on somatosensory and muscle memory to ensure accuracy.

When the line of sight is narrowed to a point in the field of vision, the relative position of the arch connecting line (thick line on the right) and the human pupil has been determined. When the pupil, the line of sight and the target are connected in a straight line, the relative position of the bullet launching trajectory and the shooting target is only determined by the included angle between the two straight lines AD and BC in the figure, where BC is the straight line connecting the pupil and the line of sight, and AD is the straight line connecting the bullet bag and the arched door.

To ensure the shooting accuracy, it is necessary to keep the straight line CB and AD at the same included angle every time, or to ensure the distance from the pupil (point C) to the straight line AD at the same time. However, when aiming, we can't accurately perceive this distance. Only when the contact point e between the rubber band and the cheek is sensed can the position of the straight line AD be determined.

However, even after the position of cheek contact is determined, the distance from the pupil to the straight line AD is still affected by the head twist and tilt angle, and there is no objective reference index for the head tilt and twist angle, so accurate somatosensory memory and muscle memory can only be formed through repeated practice. In addition, it is necessary to form an accurate somatosensory memory of the contact point between the cheek joint and the rubber band through practice.

One method is to convert the muscle memory of head and neck twisting into the muscle memory of arm and bow holding posture, that is, to keep the bow body (straight line AB in the figure) in a certain relative position with the body by keeping accurate arm posture and bow holding posture, so that in the aiming process, in order to shrink the aiming line to a point in the field of vision, the head and neck will naturally twist and tilt to a fixed angle.
