Motion sensor-based devices are all the rage these days, but they mostly target the full swing. Can such electronics be accurate enough to measure a much smaller stroke, namely the all-important putt? Since season’s nearly here, we decided to find out with the Putt from 3BaysGSA, a tiny, lightweight device that fits in the handle of a putter and relays stroke information via Bluetooth to an Android or iOS device. As Engadget’s resident nut, yours truly put the device through its paces both objectively and in a less-than-formal way to see whether it could accurately track a stroke. Will it help you lift your putter in victory, or make you wrap it around a tree?
