Description:
The PC-Trac is a different kind of trackball -- it's ambidextrous! 

The large, high-density ball and shape of the PC-Trac case act as a natural hand rest that mirrors the natural hand contour.

Designed by CST, the PC-Track prevents the need to move your arm or rotate your wrist while scrolling or clicking.

The PC-Trac is now native USB with a PC - PS/2 adapter.
