Garmin Instinct. Optional Bluetooth, stores data locally and is accessible via USB.

Again, no. It only uses Bluetooth for "messaging, alerts and notifications" and to use the phone's Internet.

It does not sync over Bluetooth.

What the parent comment is saying is that you can connect via usb and access the data that way.

Of course, the easiest way to see the raw data is to write a python script to plot it, so it’s not exactly the most user friendly, but it’s technically possible.
