a measuring device for use in golfing is disclosed . the device employs a fixed diameter measuring wheel , a magnetic revolution sensor , and a solar powered digital display to measure and display distance travelled by the wheel . display and counter are reset to zero through the use of a phototransistor reset sensor . the device is rapidly connectable and disconnectable from a golf cart , and thus is portable . it is precalibrated , and is readily adaptable for use with a hand - pulled or a motorized golf cart . attachment of the device to an extension handle rather than a golf cart converts it for use in an independent manual mode . in a further embodiment of the measuring device , the device is programmable by the user to receive and store data corresponding to a measured dimension of the wheel , and is provided with electronics circuitry for measuring the distance travelled by the golf cart in consecutive increments in response to each consecutive revolution of the wheel .
