Putt-Trainer: A worldwide golfing innovation A golfing pro has invented a truly sensational training aid. Training with the PUTT-TRAINER is great fun, because almost every putt is holed, even after just a short training period. The training device can easily be mounted on your own putter in just five seconds, and suddenly you'll be up there putting like one of the greats. Whether you're a novice or a pro, the PUTT-TRAINER will help you to recognize the exact 90 degree putter angle for the perfect line of putt, without taking your eye off the ball and club head. Any misjudgement of the line of putt can be recognized and corrected immediately. The PUTT-TRAINER has a viewfinder with crosshairs, similar to a telescopic sight, making it incredibly easy to aim at the target. Some 50% of all shots are putting shots and as everyone knows, victory or defeat is decided on the green. Even if you only reduce your number of putts by one at every other hole, you will have achieved a sensational result. The PUTT-TRAINER is barely larger than a cell phone, weighs only 54 grams and should have a place in every golfing bag. This high-quality training device would also make a wonderful gift for a partner who enjoys golf.
