The "VCS" Vibration Control Stabilizer incorporates a free-floating "teflex" mechnical vibration control system positioned between two compartments of vibration control material. Not only does this system dampen the sound and the forward shock of the bow, but the teflex system controls side to side shock and vibration. The "VCS" contains no fluids, so extreme cold or heat cannot effect this system.

The 6 1/2 oz is an Aluminum Hydraulic
The 10 ox is also an Aluminum Hydraulic
