Hi All,
On the subject of compass choices the magnetic needle gets my vote;=20
no batteries. For cross-country travel in foggy or cloudy weather I like=20
a Silva
compass which can be pinned to your chest (with a second safety pin=20
attached because the compass pin can open when pushing through dense=20
brush). But don't have an eversharp pencil nearby; as in your shirt=20
pocket. The metal in these can pull a compass 70 degrees. My eversharps=20
likely date back to the 80s or earlier. This may not apply to more=20
recent models.
