The BIGtrack is a mouse replacement and has a 3 inch trackball which makes it the largest trackball available.

The large ball requires less fine motor control than a standard trackball and it is ruggedly built. It has a left and a right mouse click button located behind the trackball to avoid unwanted mouse clicks.

The BIGtrack also allows for 2nd Mouse Connection, meaning both the BIGtrack and a second mouse can be connected allowing simultaneous participation.

The bright large 3" trackball helps to make mouse movements easy and accurate, while the oversized buttons make mouse clicks simple for those with poor motor control.
