The Marshall CVM-3 is a four-point vibration absorbing bracket (1/4" to 1/4" screw holes) for use with any 1/4"-20 screw mount system to provide stabilization when using Marshall's CV503, CV506 and similar micro broadcast cameras in action sports applications. It features 1/4"-20 pass-through holes on the top and bottom so you can mount the camera on top while attaching the bracket to typical various supports. The rubber grommets of the CVM-3 are designed to absorbs vibration.
