The Marathon Field Computer is a full-featured rugged mobile computer that combines the ergonomics of a PDA, a 7 inch screen, and the processing speed of a laptop. For supply chain applications, the Marathon allows a supervisor to resolve exceptions in real-time, at the location of the issue, saving time for both the supervisor and the worker on the floor. In addition, field service workers can realize time savings on nearly every task throughout a typical call that accumulate throughout the shift, resulting in saved time that can be used on an incremental call each day. The Marathon also gives I.T. a no-hassle integration with Windows-based applications and management systems, saving time and resources.
