Help me to supplement the knowledge of compound bow, such as how to match the relationship between the number of pounds of each accessory and the type of arrow.

There are many accessories of the compound bow, which must be equipped with: arrow platform, sight, diffuser, shock absorber and peephole. Optional accessories include: arrow pot, arrow box, bow bag and bow box. There are many kinds of accessories of each type, so I won't list them one by one. I just want to talk about the function of each attachment. The arrow platform is installed on the bow, and its most important function is to support the arrow until it is shot out. The bow string is provided with an arrow landing point, the arrow tail is located at a fixed arrow landing point, the arrow body is located at the arrow platform, the target, the arrow landing point and the bisector, and the saw of the compound bow is also fixed, thus ensuring the same force on the arrow every time and ensuring the accuracy of the compound bow. Similarly, the spreader is also an accessory to ensure the accuracy of the composite bow. Using the spreader to pull the string can ensure the minimum impact on the bowstring at the moment of deployment. In addition, unless a special hand is used for compounding, the general compound bow must use a spreader, because the low precision of hand unfolding is secondary. If the fingers do not simply pluck the bowstring when unfolding, the string will fall off, that is, the string will fall off from the groove of the pulley and can only be restored with a bow opener. Of course, the shock absorber is used to absorb shock, and the shock absorber is not installed to hurt the bow piece. The peephole is installed on the string. After opening, look at the sight installed on the bow in the peephole. There is a aiming needle. This should be adjusted by yourself. For example, the first needle reaches the bull's-eye position 20 meters, and the second needle reaches the bull's-eye position 30 meters. Because the arrow is a parabola, the number of pounds of the compound bow is also adjusted by itself, so the aiming should be adjusted. Draw the bow and cover the aiming needle of the peephole. The aiming needle points to the bull's-eye, and then pulls the trigger of the dispenser. Archery completed.

As for arrows, compound bows can only use rubber arrows, not real arrows. The arrow shaft can only be made of carbon, carbon fiber and aluminum. Aluminum arrow can be bent or not, and it is the safest shaft. Fiber shaft, check whether the shaft is injured before shooting. If you don't find the injury, shoot the arrow. The arrow will not be able to withstand the thrust of the bowstring, and it will break before shooting, and then the broken arrow will usually be directly inserted into your archer. The relationship between the weight of the arrow and the number of pounds of the bow is 6 reams/pound. Is to increase the weight of 6 grains of arrows per pound of tension.
