The Tremor Compound Bow by Bear Archery is loaded deep with all the features necessary for a successful day of shooting. The S13 single cam adds a little smoother feel, but still feels fast as ever. The cam is also equipped with a rotating module that can be adjusted without the use of a bow press. The Tremor features Bear's popular removable rubber grip for more shooting options. Bi-Dimensionally string suppressors produce an amazingly quiet shot every time.
