LOGITECH Trackman Vista

TrackMan Vista (1994) took trackball ease to new heights. Use just one finger to rotate the trackball. Your other fingers are free to use the top two buttons and the primary side thumb button without causing accidental cursor movement. TrackMan Vista gives you the advantage of three buttons and includes MouseWare software, which lets you assign draglock, double click, or another frequently-used command to one click of the third button. Customize your cursor. The Smart MoveT feature automatically places the cursor on default selection boxes.
