A pneumatic tube that is secured to the bow and bowstring with an arrow and piston inside for safe drawing and firing of an archery bow. When the archer looses the string and it drives the arrow forward, the piston creates pneumatic air resistance like a hand operated bicycle pump. This resistance is sufficient to prevent damage to the bow and / or its components from loosing the string without an actual arrow on the string. Normal loosing the string without an arrow on it is called “dry-firing” and would damage the bow and / or its components. This tube is attached to a bracket that is affixed to a mounting block that can be fastened to the front of the bow at the standard stabilizer mounting hole. There is also a laser mounted in the end of the tube, which can be turned on by the archer and projects a laser light on the target. This light is automatically turned off as the bow is fired, thus showing the archer exactly where an actual arrow would have hit. This device can be used without removing or disabling the arrow rest and is used in practice and to identify and then rectify any release flaws and other shooting maladies.
