DuoTrac is a multi-point, motion-tracking, portable sensor device and mobile app that can be used in golf to improve your swing performance. It comes with 4 sensors: 2 sensors are attached to the club and 2 sensors are on the players hips.

The idea is to better capture what’s going on at more points in the swing, or more precisely what’s going wrong. DuoTrac reports data on clubface path, transition, face angle at impact and weight shift. Linked to your smartphone, the app assesses address position, backswing, downswing and impact with distinct thumbs-up/thumbs-down icons. The app also provides instant tips to attack trouble areas.
