As it turns out, you can actually wear your tracker in your pocket, but there will be some inaccuracies in terms of the heart recordings. But this will be enough to record such things as steps and various physical activities that you perform throughout the day. The most important thing to remember about this modification is that there has to be some kind of continuous skin contact in order for the electrodermal activity to send the right kind of signals to the heart and cardiovascular system. So basically, you will only be working the motion sensor to record steps and activities, which does help to provide long battery life since the sensors are not having to work so hard. Another thing to keep in mind is that these units are almost always arm-based tracking products as opposed to straps or clip-on. This could also mean that even some of the motion sensor mechanics may report inaccurate readings since the unit is programmed to record the arm first and then the other limbs that you use each day. So it is best to turn the HR off if you want to wear the unit in your pocket. Of course, if you are only wanting to record your steps, this is a perfect way to keep the unit on you and reflect that information without all of the other readings as well. You may find that it helps to clip the unit to your waist since it can get rather clunky when inside the pocket.
