ABSTRACT:
A distance measuring device that can be easily retrofit to a recreational vehicle includes a sensor unit that easily attaches to the wheel of the vehicle, a counter unit (12) for processing the sensor signals, a display unit (13) for providing a numeric display of the distance traveled, a reset unit (14) for allowing the vehicle operator to reset the count to zero and to initiate a timing cycle, during which timing cycle movement of the vehicle must either start or continue, and a time limit unit (16) for automatically resetting the timing cycle to lengthen the cycle under appropriate circumstances. The timing cycle will terminate when no sensor signals are received during the timing cycle, and as a result, the counting circuits and the sensor will be driven low to clear memory and preserve power.
