This is the Robitronic Lap Counter System with Three Transponders.

FEATURES: Robitronic's Lap Counter is a fully operational lap counting
            system for all RC-Models of all size.  The transponders are
            extremely small and can be mounted without a problem in
            mini RC cars.
_         Each tiny and featherweight transponder is encoded with a worldwide
            unique number. By crossing the start/finish line the emitted
            signal will be recognized and processed by the receiver module
            to the lap counting bridge.
          The system is capable of processing many transponders simultanously
            and independent from the number of receiver modules installed. The
            number of receiving modules required just depends on the track
            width under the counter bridge.
          For indoor and outdoor tracks
          Works with unlimited number of cars running at the same time
