The Tempo Trainer 911 is a vintage Golf Swing Tempo Training Aid designed for advanced adult golfers. Made with DNA material in the United States, it offers wireless technology and a lifetime warranty. This analyzer is best for all aspects of golf, providing feedback to improve tempo and swing mechanics. It takes (4) AA batteries (not included). It did power on when batteries inserted. I have no idea how to use. Includes the trainer and the carrying case. See pictures.
