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). Most users will find that movement becomes intuitive within a few minutes of use, with the level of control increasing over time. The large 57 mm diameter weighted trackball produces predictable, quick, and precise cursor control. The L-Trac provides users with a precision, high performance pointing device. The programming software can also be used to disable or reassign any or all of the on-board buttons when used with external switches in an assistive application. In addition, two 3.5 mm jacks permit the attachment of two external switches which can be programmed to perform an additional two actions, resulting in full 5-button functionality. A wide light touch scroll wheel or cylinder is readily accessible, located above the center button. 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. The L-Trac features an optical laser sensor that offers "button selectable" tracking resolutions of 400, 8 CPI, easily changed on the fly. The X-Keys L-Trac Black Trackball from PI Engineering combines a high level optical sensor capable of resolutions up to 1600 CPI (counts per inch) with a robust build and history of durability, reliability and performance, carrying on the legacy of the L-Trac and PC-Trac Trackballs formerly manufactured by Clearly Superior Technologies.
