Take the guesswork out of your golf swing and perfect it instead, with the SKLZ Smash Bag. Simply fill with towels, rags, old shirts or even birdseed for an ideal training tool for the beginning and intermediate golfer. The Smash Bag provides visual feedback on the quality and accuracy of impact. All you have to do is line up and swing, then take a look at the angle of the target map to see how you did. If your swing was true, the bag will remain aligned. If your swing missed the target or hit it at a skewed angle, the bag will retain the depression for further analysis. Eliminate fat and thin shots, cure slices and improve your golf game.
