Although you can have multiple fitbits connected to your account, they have to be different types. So, I'm afraid you can't have 2 Surges connected.

You can swap between them by going into the add device process. It will detect that you are trying to add an existing Surge and will ask if you want to replace it.
Make sure you sync before each swap else you'll lose data.
