Bubble in compas

[nigelmercier]

You are sure white spirit is a suitable fluid?

Seems unlikely, white spirit is Naphtha (petroleum) hydrodesulfurised heavy.

My port compass got a bubble last year, now it is empty

I've been told mineral oil or Ethanol, but I'm going to ask Suunto for their advice.

Isopar M MSDS below, still none the wiser. VIC!

Please don't make the mistake I did, as I mentioned on page 1 of this thread but it seems worth repeating, my Plastimo Contest compass had a bubble for a few months and seemed fine, then when I actually needed the thing in fog it had emptied overnight and was ************ useless !

How long had it been useless before you noticed this in the fog?
I don't think fog causes compasses to empty.

Chewi,

the thing emptied overnight, Saturday - spiffing, Sunday - knackered !

I don't think the fog had a vacuum effect, but could be wrong there as well.

thingy robinson of robinson compass adjusters in hamble has probably seem more compasses than anyone else in the world!

He told me to use white spirit.

I did and it worked.

I done it another twice on different compasses, and that worked too. If that's the "wrong" fluid, I like that kind of wrong.

With a compass like yours that is emptying though, that is the next level of broken. The ones I did were bubble that occurred after extreme weather and were stable in size.
