Description

The original PC-Trac is re-born again as the L-Trac high performance laser optical trackball. Utilizing the latest in laser navigation technology, the L-Trac has selectable resolutions of up to 1600CPI, which are "button selectable", allowing rapid changes of sensitivity. The high performance laser navigation system is capable of tracking at greater than 20 inches per second. This means the user can "fly" around the screen with a flick of the finger or snap from one side the the screen to the other with a healthy flick of the arm. Either way, this precision, high performance pointing device produces predictable, quick and precise motion that becomes intuitive in a few minutes of use. The scroll wheel is smooth and readily accessible, located above the center button. The CST2545-5W(GL) can be fitted with two external switch jacks allowing the use of 5 buttons for added flexibility. Superior-X Button Control software (included), allows the user to set different button settings depending on the application. This allows control of applications, such as media players, directly from the trackball (volume control via scroll wheel, etc.), putting maximum control at your fingertips. This performance coupled with the natural contour of the L-TRAC makes these trackballs Clearly Superior for all applications including general computing, gaming and Computer Aided Design (CAD). CAD users love it because you can drag a line one pixel even on today's high resolution displays of 1920X1080. The shape of the L-Trac acts as a natural hand rest mirroring the natural contour of your hand. Designed to easily accommodate either right, or left handed users and different size hands. No need to move you arm to rotate your wrist from side to side. Flexibility, reliability and performance made in the United States of America. Website: www.clearlysuperiortech.com
