Magnetic reading glasses foul up compass calibration

[morgus]

So I kept getting compass error when calibrating mr P3P. Turns out my magnetic "click goggles" reading glasses dangling from my neck fouled up the calibration. Even worse would have been had it not given an error and created a faulty calibration. Heads up.

First off, I love Click goggles. They're my favorite readers.

Secondly, yeah, there are magnets in lots of things that are easy to forget about, and the Phantom compass is very sensitive. I was trying to use my iPad cover to level out during a calibration, forgetting it has a magnet in it. Took me a min to realize why things were not working right.

Magnets are very bad but also you should keep all metal away from the immediate calibration area.
