VZProbe Contact Digitizer
This is a stick device to facilitate digitizing the 3D position of a point in space or on an object. It can also be used for establishing a coordinate reference frame. By outfitting it with an appropriate tip, it can even be used to digitize surfaces not in the line-of-sight of the tracker(s), for example the underside of a car or the inside of a cup.
