SIMPLE WAY TO REMOVE A BUBBLE IN A COMPASS: This thread comes up as the first forum hit on a Google search for "compass bubble". I hope this method that I discovered helps others: Boil water in a pot, then immerse the compass and swirl it around for one minute. Do not allow the compass to touch the bottom of the pot if the stove hotplate is still very hot. Take out the compass and pinch the top and the bottom of the oil capsule very tight using both hands. Keep pinching hard until the compass cools for one minute, then pour some cold water in it, while still pinching. The plastic will be formed to slightly reduce the volume in the capsule. This method worked on a Suunto MC-2G. To test that it will not get a bubble in the cold, I put it in a freezer at 0 deg F (-18 deg C) for a hour, and the bubble did not return. I hope that the repair holds up at extreme altitude. My Silvas and Suuntos had all developed a permanent bubble because I bring them up to 23000 feet (7000m) and -13 deg F (-25 deg C). If you try this method, please post your results.
