The arrow rests on a support wire that is held in place magnetically. Due to the incline of the rest, the arrow is always securely positioned (against the button). The BiDrop moves bidirectionally—rotating downward and toward the button—under vertical load. This completely eliminates the vertical recoil (bouncing) at the moment of release. The support wire automatically returns to its original position after each shot. The BiDrop is the only arrow rest that operates according to this functional principle. The force acting on the rest is determined by several parameters: total arrow weight, FOC and point weight, limb synchronization, limb performance, nocking point height, and the plunger setting. Because the requirements for the release moment vary widely, there are three models available with different resistance levels. Thanks to its absolutely reliable and flawless function, the BiDrop is the choice of countless top archers around the world!
