Parrymeter

Parrymeter is the electronic measurement system for ball roll on the green. Beyond speed, it quantifies what truly defines putting quality: the smoothness and trueness with which the ball rolls. It takes more than one hundred measurements per second, more than two thousand per sample and more than twelve thousand per green, and converts that volume of data into objective values that can be compared between greens and between days. It allows the greenkeeper to check the real effect of topdressing, rolling or a change in height of cut, and to prepare uniform, predictable surfaces for competition.
