First Claim
1. A golf practice device for attachment to a shaft of a golf club having a head having a drive side for engaging a golf ball, the device comprising swing speed sensing means for sensing swing speed of said golf club, light emitting means coupled to and activated by said swing speed sensing means for indicating a swing speed being equal to at least a given swing speed, and wherein said light emitting means form a visible light path indicating swing direction, and said swing speed sensing means including a plurality of weights of different masses calibrated to activate said light emitting means at different predetermined club head speeds.

Abstract
A golf practice device for attachment to a golf club having a club head and a shaft, includes a swing speed-sensing device and a direction indicating device attached to the shaft. The swing direction indicating device is coupled to the swing speed-sensing device for indicating a swing speed set to given speed value. A light emitter provided in the swing speed indicating device is activated by different inertial masses and indicates with a light trace of a visible light beam directed at the golf player'"'"'s eyes a swing speed reaching the given speed value, and the direction of the club head compared with a line on the ground. Two light emitters positioned in line with the swing direction can be provided to indicate if the club head is swung squarely in the swing direction.
