The answer is yes, there are bubble free compasses. It seems that the trick to getting a compass to not have bubbles is to use a thermo-elastic capsule which flexes and so doesn't get the bubbles.

K&R's thermo-elastic capsule is flexible, not brittle. This accomplishes two things: 1) the capsule flexes with temperature and altitude changes to keep out bubbles, and 2) the capsule doesn't develop leaking hairline cracks when you drop it (or step on it).

It seems like not many manufactures make these types of handheld compasses, but they do exist.
