Getting to know your Fitbit Surge
Wearing your Surge
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.
For best heart rate accuracy you may want to experiment with wearing the Surge
higher on your wrist, particularly when exercising. Because blood flow in your arm
increases the farther up you go, moving the tracker up a couple inches can be
helpful. Also, many exercises include frequent bending of the wrist, which can
interfere with the heart rate signal. Lastly, do not wear your Surge too tight; a tight
band restricts blood flow, potentially affecting the heart rate signal.
Specifying dominant or non-dominant hand
To improve the accuracy of your Surge, we ask you to specify whether you’re
wearing it on your dominant or non-dominant hand. Your dominant hand is the one
you use for most day-to-day activities such as writing or brushing your teeth. You
can specify this setting in the Fitbit app or in the Fitbit.com dashboard.
To make this choice using the Fitbit.com dashboard:
1. Log in to Fitbit.com.
2. Click the gear icon in the top-right corner of the dashboard and select
Settings.
3. Using the navigation tabs on the left, find and specify the correct setting for
Dominant Hand.
4. Sync your Surge to update your tracker with the new setting:
a. Click the Fitbit Connect icon near the date and time on your computer.
b. Make sure your Surge is nearby and click Sync Now.
