Is It Time To Replace Your Compass?

When should the hiker replace a compass:

1. When there is a large bubble in the compass housing.
2. When the compass body is scratched or cracked.
3. When the sighting mirror is damaged or the hinge allows for excessive movement.
4. When the compass polarity has been degraded.  For example, if you can identify that the compass is not providing accurate information (e.g., doesn't point accurately to true north.)   This could be true of an older compass.
5. When lettering on the rotating dial is worn and abraded.
6. When the rotating dial is stuck and won't freely move.
7. When the magnetic needle has fallen off it's pivot point.
