The Vector 700 Pan and Tilt Head is designed for use in the television, film    and video industries to support and balance cameras and ancillary equipment.    With its new Thin Film Drag System, the Vector 700 Pan and Tilt Head provides    the camera operator a number of unique benfits. It has a minimum 104 degrees    of tilt movement for the latest digital studio and OB cameras with long lens or    teleprompter combinations. The Thin Film Drag System is a non-contacting    calibrated system ensuring consistent drag and constant performance over an    extended temperature range from -40° F to 140° F. It offers a tailored drag    characteristic that combines a high level of control at start of movement, a    seamless transition into whip pan and instant recovery to the original drag    setting at the end of movement. Incorporating its unique patented counterbalance    system, the Vector 700 requires no time-consuming cam changes.
