Disclosed is a method and apparatus for estimating practice golf shot deviation and distance. The apparatus includes a base, an axle mounted to the base, a golf ball attached to the axle and a sensor coupled to the axle for determining motion thereof. When the golf ball is struck by a golf club, the ball and axle attached thereto rotate around a pivot point provided by the base. When the ball is struck such that it deviates from a plane that is perpendicular to the axle, the sensor detects motion of the axle along its axis. The magnitude and direction of deviation is estimated based upon the detected motion of the axle along its axis. The distance that the ball would have traveled is estimated based upon the detected speed with which the axle rotates.

Method and apparatus for estimating practice golf shot distance and accuracy

Golf travel case

A golf putting practice green with a conventional golf cup and at least one simulated golf hazard. The practice putting green includes a putting mat with a realistic putting surface, a wedge shaped incline, a conventional golf cup and at least one simulated golf hazard. The golf hole and the hazards are formed from openings in the putting mat and cavities in the incline. The incline, and the golf hole and hazards, are positioned proximate to a distal end of the putting mat. An accurately putted golf ball will successfully enter the golf cup and come to rest underneath the putting mat. An errant putt, on the other hand, may enter one of the simulated hazards which protect the golf cup, but will still come to rest at the same resting place as the accurately putted ball.
