Over the years I have had problems with several compasses that have had bubbles in them. The bubble gets under the disk and knocks it off center tying it up or gets in the way of the needle. Not sure why they have a bubble, it may be designed that way to allow for liquid expansion (but then this leads to the question, why do some have no bubble?) or lower quality made product.

I don’t buy them any more with a bubble in them, if they can’t figure out how to make a compass without a bubble in it, I can’t figure out how to pay for it.


I have a $10.00 Boy Scout compass with no bubble and it is 30-years old and working great.
