O-Trac Trackball

Large, high-density ball and shape of the case act as a natural hand rest that mirrors the contour of the hand. “Ambidextrous” design accommodates both right and left-handed users and hands of all sizes. 2-1/2" trackball provides precise fingertip control and ability to dynamically accelerate across the screen by turning the ball faster. Precision-ground ball and mirror-finished rollers deliver “smooth-as-silk” feel and effortless control. No need to move arm or rotate wrist from side to side.

Features:

• Drag lock feature allows drag and drop without holding down a button
• Scroll-lock feature allows horizontal and vertical scroll without having to hold down a button
• Dynamic gain feature accelerates cursor movement with speed of trackball; roll the ball slowly for single pixel accuracy
• Rugged ABS construction
