Which Fitbit tracker can I use with the Sense?

[Macd1995]

I want to use my Fitbit Sense for everyday and a small tracker on occasions. It looks like i can't add the Sense and the charge 4 at the same time. what tracker can i use if I have the sense?

This is from the FAQ:

"Note that you can't connect multiple devices that use the Fitbit App Gallery to one account. For Fitbit Charge 3, Fitbit Charge 4, Fitbit Ionic, Fitbit Inspire series, Fitbit Luxe, Fitbit Sense, and Fitbit Versa series, only connect one of these devices to your account at a time."

Found this because App would only allow Sense of Charge 4.  Looking for sleek tracker to wear on other wrist when I decide to dress up and put on a nice watch.

From Can I use more than one Fitbit device with the same account? 

So only options are those not listed above; i.e. nothing recent; would probably have to find a used Charge 2, Alta HR, or such.
