I expect they have on eof each or have the ability to recalibrate their electronic versions ... but it would be interesting to know ...

I used a northern hemishpere compass at the Fireball worlds in Durban ... it's not idea ...

It is true that there are different versions for north & south hemispheres ...

Reversing the polarity and reading it back to front I
guess could work but I'm no expert... best to contact
the manufacturer - it may be fine as it is. Basically in
the northern hemisphere the compass needle is pulled
down as well as towards the pole so the southern end is
counterweighted to stop it dragging on the compass body.
The opposite is true in the southern hemisphere.

Well I never knew... I know you can reverse the direction they point in by drawing a magnet along the needle - did this once by accident. Don't know if this would make it work in the Southern hemisphere?

Seriously most compasses are weighted to suit which side
of the earth you are on..... they tend to drag
otherwise. I would contact Silva to check your
compass....

Hi Adam,

Sorry to be a pain, but just to confirm your not making a funny , as I just packed it.

Will it not be possible to read it anyway?

If not, do you have an outlet in Auckland I can get one from on Saturday!

The compass won't work in New Zealand, you will need a southern hemisphere compass.
