Delivered this morning, took right at a week ordered from South Korea. Creator Combo, $3799 out the door after tax, free shipping, and no customs additional charges! Boom!!
That was the cheapest price I saw during a month of daily ebay searches...
I'm not really offering guidance. Just pointing out the seemingly overlooked possibility that you may have been calibrating the compass unnecessarily.
Not that I'm aware of. This is how compass calibrations have functioned for some years now.
Per the guide above, that's typically an indicator that you should not calibrate the compass. It normally occurs when the compass is/was near some type of magnetic metal source.
