Abstract: A bow stabilizer according to the present invention includes a body for attachment to the bow which defines an internal chamber. A guide rod is supported by the body within the internal chamber. The guide rod carries a movable part and a pair of biasing members arranged to apply opposing biasing forces to the movable part. A pair of stabilizer arms are removably connected to the movable part and extend external to the internal chamber through openings in the body. Each stabilizer arm carries a removable stabilizer weight. The movable part moves forwardly and rearwardly along the guide rod against the biasing forces of the biasing members, carrying the stabilizer arms forwardly and rearwardly within their respective openings, to counteract the bow vibration created by launching an arrow.
