The growing motion sensor segment in golf heretofore has focused virtually entirely on the full swing, but 3Bays, which itself began with a full-swing motion sensor, has now applied its technology to analysis of the putting stroke.
The 3BaysGSA Putt device weighs a third of an ounce and plugs into the grip end of your putter. Via a Bluetooth connection to an app on a smartphone or iPad, it relays information about your putting stroke. It tracks face angle, consistency, attack angle, tempo, backswing time, downswing time, impact speed and swingpath distance.
It will instantly show an animation playback of your path in both side view and top view, to see how the putter is moving throughout your stroke.
The 3BayGSA Putt sells for $200 and can be purchased through the company website.
