Product Overview: The Pure2Improve Adjustable Practice Cup is designed for use at home on your own putting mat or backyard green or out on the golf course practice green. Adjusts from a standard 4 Inch opening down to a tight 2.75 Inch opening. Weighted to stay put on any surface. Bottom adaptor pushes out for snug placement into practice green cups. Can be rotated. The Adjustable Practice Cup is designed to practice all putts of any length or break. Sinking breaking putts is all about visualizing the right line. The Adjustable Practice Cup's unique horseshoe shape encourages players to aim to the high “pro” side of the hole. Helps players improve the accuracy of their line and speed on putts of all lengths. Small hole opening makes real holes appear larger once the player is out on the course. Can use it as a practice hole (on the turf) on a crowded practice green. Features: VERSATILE WEIGHTED DESIGN - Use either as a stand-alone cup flat on any putting green at home or on the practice green at the course with enough weight to stay put or, with the flip of a switch, lower a curved component to fit the cup into any standard 4” diameter hole. VISUALIZE BREAK AND LINE - Rotate the Practice Cup on sloped practice greens toward the high side of the hole to visualize the line and develop the aim and touch to make putts of any break, length, and speed. TUNE AIM AND ACCURACY - Adjustable opening from 4” standard cup diameter down to a smaller 2 ¾” opening. Develop a precise, dependable putting stroke necessary to make more putts under stress on the course. FITS IN GOLF BAG, ANY BAG - Compact design fits into a golf bag or travel bag easily for convenient use on the practice green, back at home, at the office, or on the road.
