Better clubface control by understanding wrist angles

Wrist angles have direct relationship to the clubface.  Precise wrist data provides immediate feedback on wrist positions and makes motion learning that much faster. Check out the video by Athletic Motion Golf coaches Mike Granato and Shaun Webb explaining how they use Hackmotion in their coaching work.

Extension / flexion parameter

Ulnar / radial deviation parameter

Rotation parameter - * Beta testing phase

Wrist data after each swing

Wrist angle data after each shot

Measure your progress after each swing. Set your target wrist angles and get immediate feedback for reinforcement learning.

Explore detailed dynamic of wrist motion

Learn correct release and transition from flexion to extension. Compare you wrist motion to tour player's data.

Real-time 3D model and replay of wrist motion

Analyse each swing with frame by frame replay of the 3D hand model.

Setting up is easy

1. Put the sensor on like a wristwatch

Sensor is easily attached to the hand using adjustable size straps that are provided with the system.

2. Calibrate in couple seconds

Calibration aligns the sensor with the hand with a single press of a button.
