PuttRhythm is a fairly large board equipped with a metronome. When you turn it on, the sound starts to sync with a blink of red light and an indicator appears on the display. You can adjust the pace as you like and find the right rhythm that can help you swing better. The board itself has several protrusions where the ball has to come out, so you can practice straight line strikes. Whether placing a board with a built-in metronome can actually help you immerse one stroke probably depends on how you use it and how often you practice it. Hey, it's still just high-tech help, not magic.
