By now most golfers are familiar with all types of game-tracking gizmos that rely on a Bluetooth connection between a club-mounted transmitter — most of them screw into the small hole on the end of a club’s grip — and a smartphone or tablet app. Blast Motion Golf 360 measures face angle, loft and lie, rotation — nine metrics altogether that offer an almost instantaneous picture of where your putting motion is, and where it needs to go. But in one area in particular — tempo — it’s truly amazing. In its database are one and a half million putting strokes of Tour players, and what they’ve gathered from their input is that the backstroke time is twice as long as the through-stroke. In other words, no matter how long the putt or the stroke to match it, the perfect rhythm of a pro-level stroke is always .3 seconds or a multiple of it going back, .6 or a multiple going forward and through. And Blast Motion will show whether you’re in the ballpark in just one stroke. The “Blast Connect” cloud-based platform turns the product into a long-distance teaching aid. You can click on the camera and film the swing, and all the metrics are right there with the swing, which can then be shared with a teacher or coach remotely. It works for pitching, chipping and full swing, too.
