  This model is a 5 button model. The Trackball contains 2 ports for external buttons. When external buttons are connect the buttons on the trackball also operate making it up to a 5 button trackball. 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 high speed. 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 optional scroll wheel is smooth and readily accessible, located above the center button. Product Features:
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. Then, with a button stroke, they can fly around the screen to get general tasks done. Game players have called it an "Almost unfair advantage", citing the fingertip control and precision, high performance tracking. The combination of Superior-X Button Control and the L-Trac offers unparralled flexibility, performance and reliability. Designed to minimize the effects of contamination build up and the resultant degradation of performance, this high performance laser trackball uses highly polished stainless steel rollers. It has been found by CST that the "ruby ball sliders" used in most optical trackballs, cause performance degradation when "gunk" builds up on them. This can be annoying when playing games on-line (or anytime). The "mirror polished" stainless steel rollers do not readily collect "gunk" and are easily cleared by spinning the ball rapidly. The Dupont Delrin bearings are embedded with teflon and internally coated with a lifetime lubricant making the feel of this trackball extremely smooth and it's reliability very robust. The stainless steel rollers are extremely tough and give a super smooth feel. Life testing indicates that this unit may outlive most users. It, most probably, will be the last pointing device you will ever need to buy. 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 by Americans. The L-Trac is lead free and meets all known environmental requirements and is produced using "green" methods. Packaging is kept to a minimum and is 100 percent recyclable. Product Dimension:
Compatibility: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, Windows 98SE and ME, most versions of Linux including Google Chrome OS, MAC OS9 and later and any other USB 2.0 Full Speed compatible operating system such as Sun Solaristm. Features: Attach optional switches to these 3.5mm ports located on the front of the trackball.  Part #'s: TKB-6015-LBKBK-R |
