When/how often should compass calibration be updated?

[SBJBW]

I have an Evo Lite+ and it flies well with the initial compass calibration. I live in Santa Barbara, CA and I am planning a trip to Lake Arrowhead. It is about 160 miles away (mostly east) and at 5,000 ft elevation instead of sea level. I’m wondering if I should recalibrate the compass. Maybe the difference in magnetic declination angle is the more important factor instead of distance. The magnetic angle difference is about 0.5 degrees. Is that enough that I should recalibrate?

Generally you don't need to invest the app notices the compass deviation and notifies you.

But you can always do it for peace of mind.. Away from metal of course.

Non ho mai calibrato la bussola da quando l'ho usata
il mio Evo 1 è arrivato da carolina droni e vivo in sardegna sempre acceso e decollato mai un problema
4 anni ormai
