The perfect on the go adjustable practice cup that can be used just about anywhere. If the practice greens are crowded as they often are at the weekends, no problem, simply place down at putt away. The concept of the Adjustable practice cup is to visualise entering the cup on the right line and also improve speed from differing lengths. The unique horseshoe shape forces the player to hit the high side of the hole and avoid seeing those frustrating putts slip by low on what is called the \'\'amateur side\'\'. This will really improve your line and speed. It fits in all standard sized golf holes and has a 2.75inch opening that forced the putt to enter the hole on the high side. A great idea, so simple and extremely portable.
