The Swing Caddie SC200 Plus Portable Launch Monitor from Voice Caddie will help you dial in the exact distance you hit every club in your bag. When a pro golfer steps up to an iron shot, he knows almost exactly how far he hits that club. Are you just guessing when you approach the same shot? Sure pros are more consistent but they also have had rep after rep with a launch monitor to know exactly what their average distance is with every club in their bag. Now you can have this valuable information from a portable unit at a price you can afford.
