Getting to know your Fitbit Surge
This section tells you how best to wear, navigate, and recharge your tracker.
Wrist placement
Review these tips to make sure you’re wearing your tracker correctly.
All-day wear and exercise
Your Surge should be worn on your wrist. While it may track stats such as steps and
floors when placed in a pocket or backpack, it is most accurate on the wrist. For all-
day wear, your Surge should usually rest a finger’s width below your wrist bone and
lay flat (as you would normally wear a watch).
As with all heart-rate tracking technology, whether a chest strap or a wrist-based
sensor, accuracy is affected by personal physiology, location of wear, and type of
movement. In other words, not every person will get a perfectly accurate reading
with every type of exercise. For best heart rate accuracy keep these tips in mind:
1. Experiment with wearing the tracker higher on your wrist during exercise.
Because blood flow in your arm increases the farther up you go, moving the
tracker up a couple inches can improve the heart rate signal. Also, many
exercises such as spinning cause you to bend your wrist frequently, which is
more likely to interfere with the heart rate signal if the tracker is lower on your
wrist.
