The CG Golf Rollspeed is a putting-practice tool designed to help golfers measure and improve their putt speed control. It focuses specifically on quantifying the speed of your putts so you can develop a more consistent touch on both short and long putts. The device integrates with an app platform that lets you track and analyze your putting speed indoors or outdoors, enhancing your practice sessions. Itβs aimed at golfers looking to sharpen feel and distance control on the greens. This app also allows you to quantify distance and deviation on full swing shots.
