Why does it always asks for calibration?

[titi]

Hi! Does someone knows why the Go4 app always asks me to calibrate the compass? Even when I change batteries it gives me compass error. During flight it's not common, but I've received compass error during flight sometimes.

And sometimes I have to try to calibrate about 5 times to have success. Very strange...

Iron/steel near takeoff or strong magnet.

I understand your reply, but this is not the case!
Last time was on a wood pier over the sea!

Did the wood pier have iron bolts or reinforcements in it? Unless you already have, take it out to a grass field and calibrate it far away from any metal objects. Also curious if the drone has all firmware updates.
