How does my Motion determine whether I am at the right or left rein?
Equisense Motion calculates the average value of the rotation around the vertical axis within 10 seconds to determine the rein. In simple words, it calculated the direction in which the horse 'turns'. On a straight line, for instance, the sensor compares the rein before and after the straight line. It then knows which rein you've been on while going on the straight line.
