This is the deluxe version of the Trackball Roller II, and has 3 additional buttons on the unit; a Double Click button, a Speed Control (acceleration) button, and an X-Axis / Y-Axis Lockout button (to limit the movement to only the X or Y Axis if needed). This is truly the ultimate assistive trackball on the market today. This mouse alternative is ideal for users with severe motor-skill difficulties.

The L-Trac from Clearly Superior Technologies combines a high level optical sensor capable of resolutions up to 1600 CPI (counts per inch) with the robust build for which the original PC-Trac line is well-known. The L-Trac features an optical laser sensor that offers "button selectable" tracking resolutions of 400, 800 and 1600 CPI, easily changed on the fly. Combined with this is the ability of the L-Trac to track at speeds exceeding 30 inches per second, even at a 20G acceleration rate. An optional scroll wheel (available on select models) is smooth and readily accessible, located above the center button.

The L-Trac provides users with a precision, high performance pointing device. The large 57 mm diameter weighted trackball produces predictable, quick, and precise cursor control. Most users will find that movement becomes intuitive within a few minutes of use, with the level of control increasing over time.

The level of performance and range of features, coupled with the proven contour of the L-Trac makes these trackballs an appropriate option 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 high resolution displays. Then, with a button stroke, they can fly around the screen to get general tasks done. Gamers have called it an "almost unfair advantage", citing the fingertip control and precision, high performance tracking.

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. The L-Trac uses mirror polished stainless steel rollers do not readily collect unwanted material 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 user-replaceable stainless steel rollers are extremely tough and designed to handle hard usage yet still provide users with controlled smooth movement.

The L-Trac is now available from PI Engineering as the X-Keys L-Trac

Clearly Superior Technologies just added a cool factor to their line of L-Trac high-performance trackballs. The new L-Trac GLOW offers all the same functions of other L-Trac models but with a unique new look--a backlit translucent ball that glows a vibrant blue.

The L-Trac GLOW uses the same quality components that have enabled Clearly Superior Trackballs to develop a reputation for reliability and performance under demanding conditions. The precision-ground ball and mirror-finished rollers deliver a smooth-as-silk feel and effortless control. The ball on the L-Trac GLOW is 28% lighter than the traditional ball used in other L-Trac models, resulting in a reduced load on the fingers.

The L-Trac GLOW features high performance laser optical tracking with selectable resolutions of up to 1600 CPI. Button selectable resolutions enable rapid changes of sensitivity while maintaining full control of the trackball. 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 of 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 design is completely ambidextrous, accommodating either right or left-handed users. The extra large ball and contoured profile allow for easier control and accommodate hands of all sizes--from children's to adults'. The lighter weight of the ball on the L-Trac Glow makes it a good option for children or those who have limited strength in their fingers.

Performance users can expand their command options by selecting the CST2545-5WGL-RC. This model includes jacks to connect two additional external switches.
