Compass oil

[to...@seanet.com]

Well, I finally looked into fixing the air bubble in my US Divers compass.
There's a little screw with an o-ring that gives access to the oil. What's
inside smells and feels like a light petroleum-based oil.

Anyone have an idea how I'd go about getting similar oil to fill in the air
bubble?

Thanks for any ideas!
Lars

I'm sure a local dive shop could point you in the right direction (just in
case you don't get a cheaper option here).

You could probably use Marvel Mystery Oil, which is commonly used for
things like sewing machines or air tools.

I don't know specifically about diver's compasses, but I've used mineral
oil in my boat compass successfully. Art.

Lars, US Divers will replace the thing/squirt some oil into it if it isn't
too old. I would just call them and ask to get a small bottle because you
will need more again. I wish I knew why liquid compasses leak so regularly. I
suspect the oil actually soaks right through the solid plastic walls.

I have some oil for my sailboat compass and that is what I have used to
refill a US Divers compass and it works fine. So, you might want to also call
a sailboat supply store.

The oil in your compas is probably silicon oil in a good divestore you must
be able to get some new oil drain the old oil and fill the compas again
only using the new oil.

There are probably several different oils that are used in compasses and
gauges. I believe most are silicone based today. You can get compas oil for
filling marine compasses from your local marine store (They might have to
special order it.) or you could check with a marine compass repair and
adjustment service.

Just a thought. Depending upon how large the bubble is, it might be a helper
indicator to let you know that it's horizontal so it will register easier.

When I asked the shop about the same problem with my Suunto, they
simply replaced it. Maybe THAT'S the solution. (No pun intended.) Even
if you can get the liquid - how are you going to get the bubble out??

Just perform the repair while its its sumberged in oil:

1. Put the compass assembly in a small pan.
2. Cover it with oil.
3. Get rid of the bubble inside the compass.
4. Close the compass up.
5. Remove compass from oil-filled pan.
6. Clean.
7. Dispose of the unused oil.

FWIW, compass assemblies are pretty cheap and usually not worth
the hassle of a DIY repair.
