Abstract:
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.
