Can we release compound bow with our hands?

First of all, it is generally acknowledged that hand release can cause great disturbance to the bowstring. Since the tension of a compound bow is very large, even a slight disturbance of the bowstring will have a great impact on the accuracy of the arrow. Secondly, the bowstring of a compound bow is fixed on the guide wheel, and most guide wheel grooves are narrow and shallow. Therefore, if the disturbance caused by hand release is too large, it is likely to cause the bowstring to come out of the guide wheel groove, which can cause permanent damage to the bow and the guide wheel. The main difference between compound bows that can be released by hand is the guide wheel groove. The wide and deep guide wheel groove can prevent the bowstring from coming out of the groove to the greatest extent. However, the influence of bowstring disturbance on shooting accuracy is still there. Of course, these are all within the range that you can bear when the poundage of the compound bow is within your tolerance! If the poundage is too large, you want to try hand release. Not to mention the damage to the bow, before the bow is opened to the effort-saving ratio, your hand will definitely be injured by the bowstring, and it is easy to cause tragedy when you can't bear the pain! So it is recommended that you use a release device!
The difference between release devices

Release devices are divided into grip release and wrist release. Compound bow release is generally divided into grip release or wrist release. Grip release can be handheld or hinged. Grip release is sensitive, reliable and accurate, but it requires considerable training to master. Generally, novices start with wrist release. Wrist release can be divided into hard rod connection or soft belt connection, and can also be divided into clamp type or hook type. The choice of these types is largely based on personal characteristics. I personally feel that there is a slight difference between hard rod and soft belt when shooting. Sometimes moving the index finger during shooting will drive the hand. In this case, the soft belt seems to have less impact, and the length of the soft belt is also easier to adjust. The basic length of the hard rod is fixed, but the hard rod is worse than the soft belt in terms of consistency of positioning. The clamp type is theoretically not as accurate as the hook type, but it is not easy to get out of the hand when drawing the bow and is safer.

There are two types of wristbands: magic glue and card hole. The magic glue must be stuck to the same position every time, otherwise it is difficult to ensure consistent positioning. The card hole is relatively simple and can be stuck to the same hole every time. Secondly, it is difficult to keep the same friction level on the wrist skin. For example, air humidity, sweating, and even different fatigue levels can cause the hand shape to change, causing the wristband to slide on the wrist. Therefore, it is important to keep the wristband in the same position every time to ensure that the finger touches the trigger position and the action is consistent and gentle. The trigger action can cause a 2-4cm dispersion difference at 18 meters.
