The Ontrac, is a complete training system (in one simple tool) for all parts of your game. It was developed in conjunction with PGA Teaching Professional, Ross Kroeker to help the golfer achieve the proper club position in the two most important parts of the swing, the takeaway and the impact zone. Most swing mistakes occur in the first 18 inches of the backswing. The Ontrac is designed to provide a visual and physical guide to help you start your swing correctly and return the club back Ontrac through impact. In addition, the Ontrac will help you with 3 critical elements of your swing: club face position, swing path, and swing plane. All 3 of these elements are related and, if you make a mistake with one, it often leads to a corresponding correction or mistake with the other. Ontrac provides a simple yet effective guide that enables you visualize the full swing and eliminate these mistakes. When it comes to putting, the Ontrac is second to none in providing a tool to groove both your aim and tempo. Finally, the Ontrac provides a bounce board for a physical guide to getting out of the trap. From the driver to the putter, the Ontrac is the most functional tool to improve your game, and better still the designers have managed to make the Ontrac l super durable, lightweight and compact, so that it is easily carried in any golf bag. The patented dual density injection molded design provides for optimum performance. The panels combine the wear and impact resistance of ABS with the durability of TPU, an injection molded rubber compound. The hinges are over molded with pure TPU to form a highly flexible and durable living hinge mechanism. The Ontrac weighs just 2.4 pounds. The ABS/TPU panels are soft so that they will not damage your clubs, yet we are so confident in the durability of the unit that we guarantee the unit cannot be broken through its normal use. The Ontrac comes with a 15 minute instructional DVD, as well as 24 pages of drills and instruction from PGA Teaching Professional Ross Kroeker
