The caption is particularly useful.
A friend of mine had his compass buggered up by being in a rucksack with a mobile phone. I do always carry a spare compass, but I tend to keep them in the same place if I'm not using one, so if one goes wrong, the other one probably will too.
Just as well I've got my GPS ...
