The HackMotion sensor should be worn on the lead wrist:
Sensor on the lead wrist of a right-handed golfer

Sensor on the lead wrist of a left-handed golfer

Try each size hand strap to find the best fit. The fit should be comfortable, while tight enough to prevent the sensor from moving during a swing.

To change the strap, push the sides of the rubber on strap and remove the sensor, then insert the sensor in a new strap.
Make sure that:

Unlike earlier sensor versions, HackMotion Sensor 4 does not have a glove clip attachment. It is designed to be worn under a golf glove.
Make sure that your HackMotion is:

Wearing with a strap around the palm
You can use the HackMotion Sensor 3 in two ways – either attach the provided clip to your golf glove or attach the strap to the palm of your hand without a glove.
Which one you choose is down to personal prefference.
However wearing the HackMotion sensor with the hand strap tends to provide more accurate results, especially if your glove’s velcro is worn out that may cause the sensor to move around.
