Hank Haney Planefinder Golf Swing Trainer. The Hank Haney PlaneFinder is for golfers who want to improve their swing. The beauty of the PlaneFinder is that you find out immediately what you"re doing right and what you"re doing wrong. And then by making subtle adjustments to the swing, every golfer can quickly discover their proper plane and how to remain on it. There"s a big difference between feel and real and the Plane Finder never lies. It"s the next best thing to having a personal lesson with Hank Haney! The concept of swinging the golf club on the proper plane was first articulated by Ben Hogan in his classic 1957 instructional book, Five Lessons: The Modern Fundamentals of Golf. Years later, legendary teacher Hank Haney has made swinging on plane the cornerstone of his work with Tour players and high handicappers alike. And now, along with inventor Rusty Pies, Haney has created the PlaneFinder, a unique and innovative device that provides immediate feedback if the club deviates from the proper plane on both the backswing and downswing. Tour players and golf instructors alike know that swinging on the proper plane is the key to effortless power, laser-like accuracy and, most of all, consistency. Golfers can improve all of those aspects in very short order as their swing plane improves. Not only can they use the PlaneFinder during practice sessions at the range but at home as well. And, the PlaneFinder works equally well with every club in the golfers bag, from lob wedge to driver. The PlaneFinder is available in both a right-handed and left-handed model. The PlaneFinder is portable, lightweight, and can be used anywhere-the home, office or at the range and will groove and improve your swing right away. Dimensions: 30" L x 12" W x 24" H; 4 lbs.
