From your previous posts, I see that you have used a Fitbit before so am surprised you would not already know the answer. And I would think you would at least realize it is not just generic "fitbit" but different models with different features.
Does your question apply to any specific Fitbit model?
Hello @SunsetRunner
Maybe these two links will explain what your looking. How to use GPS: https://help.fitbit.com/articles/en_US/Help_article/1874.htm. Which activities does my Fitbit device track automatically: https://help.fitbit.com/articles/en_US/Help_article/1785.htm
@SunsetRunner to give you an answer for your specific fitbit model, we will need to know what model you have
Yes you can use the gps tracking feature found in the fitbit app.
Yes, if your tracker has built in GPS, like the Sense, Versa 3, some Charge Models, etc, you may be able to track from your wrist.
Some models you will need to carry the phone to use the connected GPS
