Using the magnetometer
Just what the title says.
Mini 2 and Mini 2 Pro have a magnetometer that gives tracking direction an extra reference, extending the interval between resets. It is off by default; we recommend enabling it for everyday use.
If your environment has a lot of metal, such as a spring mattress, leave it off initially. Briefly approaching metal objects can be corrected automatically, so that alone is not a reason to turn it off.

Is extra calibration needed?
The magnetometer automatically collects data during everyday use. You normally do not need separate manual calibration each time. Put on your Trackers and perform Full Reset and Mounting Reset as usual.
