Why the B-Stinger Works
To understand why the B-Stinger works, we first need to define the role of a stabilizer in archery. A stabilizer should hold your bow steady both while at full draw and at the time of release while shooting. The B-Stinger embodies the definition of stabilization. When an archer is holding at full draw, there are many forces built up in the bow string, cables, limbs, the arms, hand and back of the archer, etc. When the arrow is released, these forces change suddenly. These changing forces end up pushing and/or rotating the bow affecting the flight of the arrow. The job of the stabilizer is to minimize the movement of the bow resulting from these forces.
The way to decrease something's movement when a force is applied is to make it heavier. If rotation (i.e. torque) was not a factor, the answer would just be to increase the weight of the bow. But with rotation, weight is much more effective if it's moved away from the center of rotation. That's why tight rope walkers use a long pole instead of a short baton. The design of the B-Stinger has as much of it's weight as possible in the stainless-steel disc at the end. The B-Stinger also uses a light but rigid carbon fiber rod to connect the disc to the bow. This is also important for the following reasons. If the connecting rod was heavy it would make the bow heavier but not help much with stabilizing. Also, if the rod was flexible (or had a flexible section as some other stabilizers do) than any weight outside the flexible section would be less effective. This is because the flexible section would have to load up (i.e. finish flexing) before the outside weight fully helped to stabilize the bow. By this time the arrow is long gone.
So the B-Stinger works because the weight is concentrated at the end and the connecting rod is light and rigid. Those are the qualities you want in a stabilizer and since they're patented, they exist only in the B-Stinger.
