Practice your golf swing without shattering your neighbor's window. Even tells you the distance and accuracy of your shot.Golf is not a game, it's a way of life. Whether you are a golfer orsomeone close to you plays the sport, then you know what we're talking about. That's why the MasterSwing is the perfect gift for the golfer inside of you or someone you know. In fact this particular item is in honor of my dear friend andneighbor, Jeffrey, who has set off every car alarm in the neighborhood. Thankfully with plastic golf balls only. Unfortunately he has been relegated to practicing his swing more often on the front lawn than at the course, due to the birth of achild. The only problem is that plastic practice balls aren't the real thing. And gosh darn it, I feel his pain every time a shrub eats a ball or a car runs one over. With the MasterSwing, Jeffrey not only gets the feel of a real golf ball, hefinally gets to pull out his driver for long range practice. And he'll know the precise distance of each shot with an electronic readout. Even tells you whether you hit a hook or a slice. It's a lot like having your own caddy telling you which club toselect for your shot. Great for indoor or outdoor practice. You'll never have to chase balls again or worry about breaking a window. Even includes a rubber mat with built-in tee placement. For those days when you don't have time to get to thedriving range - or when Mother Nature won't permit it. From a driver on down to a 9 iron, you'll never miss out on an opportunity to practice your swing. 3 AA batteries not included for distance readout.Measures: 12 1/2" x 13" x 8"
