The Manfrotto 303PLUS QTVR Geared Panoramic Head Kit is the same as the 303 kit, but incorporates precise geared movement of the two sliding plates used to locate the camera over the panoramic axis of rotation, adding greater accuracy to nodal point positioning. The plates are also longer than those of the 303 head, which helps to make this head suitable for use with larger traditional or digital SLR cameras equipped with standard or wide angle lenses, or for medium format cameras.
