For years, professional golfers have practiced putting to targets smaller than the regulation 4.25″ hole. The drawback? No audio feedback. The Putting Peg & Pod now give you that important feedback. When struck, you will be rewarded with the sound of the ball falling into the hole! This 3 step system is guaranteed to improve your putting. Begin with the largest ring 3.25″, then move to the smaller 2.25″ ring, and finally practice to the Peg (1.25″) by itself. Improve your putting with The Putting Peg & Pod! Two years in the making. The Putting Peg & Pod are 1.25″ inches in diameter, and has a state-of-the-art and patent pending mini-speaker system that is fueled by three powerful Toshiba quartz batteries. Once the aid is bumped by a golf ball, a motion sensor within the unit immediately activates the MP3 sound file and the golfer is rewarded with the sweet sound of success, the sound of the ball rattling in the bottom of the cup. This design was over two years in the making, with Fuzzy testing a number of prototypes before perfecting the sensitivity of the motion sensor, as well fine tuning the volume and clarity of the sound file.
