Abstract
A golf practice device comprising a mat with at least two sensors arranged therein in the direction of a swing orbit of a head of a golf club. A swing time substantially from a start of a back swing to a point of an impact with a golf ball is calculated in response to signals output by the sensors, and the result is indicated so that a golfer can observe same and thus achieve a stable swing. It is possible to distinguish an address motion and an actual swing before impact by adapting a special combination of the outputs of the two sensors.
