The Quad combines our innovative Bumper technology and four powder filled chambers to produce a stabilizer that provides multi-stage dampening. The shock absorbing and vibration reducing action starts with three powder filled rods, continues to the Bumper that allows the stabilizer to "flex" and ends at the main powder filled chamber. The three active stages provide an outstanding reduction of shock, vibration and torque over the widest range of harmonic frequencies. In addition, the three rods also put the weight away from the bow giving the shooter the advantage of having a longer stabilizer without the extra weight for added balance.
