HACKMOTION
Several Tour pros and Top 100 teachers have embraced this amazing device, which measures the wrist motions that make or break every golf swing or stroke: flexion/extension (the “flapping” motion) and radial/ulnar deviation (the “side to side” motion when your hand is held in front of you). Its small sensors wrap quickly and easily around the lead wrist and fingers (except the thumb); when connected to the Hackmotion app via Bluetooth and after a moment’s calibration, the measurements begin and the feedback in degrees is immediate, with a very instructive graph produced that shows how the wrists, and therefore the clubface, deviate from the target line through the swing. It’s like nothing else out there.
