Abstract: The abstract is of an archery bow compensator comprising a central rod or core that is threaded at its trailing end into a bow to extend forwardly therefrom. A chamber at the forward end of the rod may be loaded with pellets to balance the rod precisely in the archer's hand. An inertia sleeve carried on the rod moves forward when the bow string is released against the force of a compression spring. When compressed, the spring thrusts the sleeve back against a stop on the core to force the bow firmly into the Vee of the archer's hand against any tendency to jump out.
