I don't know what kind of bow they use, but it sounds like an antique. Martin, who I love so much, with his cheetah, was able to shoot gnats off a fly's butt without damaging the flesh (that might be an exaggeration). The new bow Martin sent me was not another cheetah as they changed their line even though they honored the warranty and sent it to me. albeit a step better , I didn't feel like that.
